June 2

The Children — Melissa Albert (William Morrow)
Guinevere Sharpe has two childhoods. In one, she and her brother, Ennis, live in the wooded shadow of their family’s isolated Vermont farmhouse; in the other, the pages of their mother’s world-famous Ninth City books, where their magical adventures have made them household names. In reality, Guinevere’s childhood isn’t the enchanted idyll her mother’s readers imagine: she and Ennis are growing up near-feral, unwashed and underfed, escaping each day to the wild woods they’ve made their playland. As Edith Sharpe’s books explode into epic popularity, the threats of a rural childhood give way to the escalating perils of fame—until the night it all goes up in flames, leaving Edith’s series unfinished and her children the sole survivors. Now an adult coasting on her mother’s name, Guinevere is mid-promotion for a ghostwritten memoir when her estranged brother, an artist who has until now spurned his family’s legacy, announces an upcoming installation titled, simply, Mother. As rumors swirl around a death connected to his last show, unsettling recollections from Guinevere’s childhood begin to surface. Her public facade starts to crack, forcing her to confront the questions she’s spent the last twenty years running from: What really happened the night of the fire? And what dark history lies behind their mother’s fantasy world?

Hunger and Thirst — Claire Fuller (Tin House)
1987: After a childhood trauma and years in and out of the care system, sixteen-year-old Ursula finds herself with a new job delivering mail at a local art school, a bed in a halfway house, and some new friends, including wild-child Sue. When Ursula is invited to join a squat at the Underwood, a mysterious house whose owners met a terrible end, she can’t resist this hodgepodge family. But as Sue’s behavior and demands become more extreme, Ursula, who has always been hungry—for food, but more importantly for love and acceptance—carries out her friend’s terrible dare. And, for this, Ursula finds herself literally haunted. Thirty-six years later, Ursula is a renowned but reclusive sculptor living under a pseudonym in London when her identity is exposed by a true-crime documentarian researching an unsolved disappearance. But the filmmaker is not the only one who has discovered Ursula’s whereabouts, and as her past catches up with her present, Ursula must work out whether the monsters are within her or without—and if they will finally make her pay for her past mistakes.

The Typing Lady: And Other Fictions — Ruth Ozeki (Viking)
A college student falls for her professor and learns to transmute longing into language. A disquieted husband watches with tenderness and unease as the ghost of his wife’s ambition roams the woods outside their home. A long-deceased Beat poet hijacks the mind of a young publishing assistant during a sales meeting, railing against the state of modern literature. A curious grandmother creates a fake online dating profile to spy on her granddaughter’s romantic life—and sets in motion a deception she can’t control. Spanning eras and geographies—from a New England college town in the 1970s to downtown Manhattan in the 1990s to a moss-covered Pacific Northwest island during the early pandemic—The Typing Lady is an electrifying meditation on the stories we tell ourselves, the stories we abandon, and the stories we become. Threaded with the tactile ephemera of writing—typewriters, letters, manuscripts, and disappearing ink—the book reveals how we record ourselves in language, and how language, over time, records us in return.

The Thinning — Inga Simpson (Akashic Books)
Fin grew up by an observatory, learning about telescopes and planets, inspired by the passions of her mother and father, then leaders in their fields of astrophotography and astronomy. Those days are long over. Now Fin, her mother Dianella, and a band of outliers live deep off the grid, always on amber alert and always ready to run. In the outside world, things are not good: extinctions and a loss of diversity threaten what’s left of the environment. With a new disaster looming, Fin finds herself thrust into an unlikely partnership with a stranger who has appeared in their camp. Terry is one of a new breed of evolved humans, the Incompletes, who are widely distrusted. But the pair will need to work together during a dangerous journey if they are to play their part in a plan to help restore the natural world—and humankind.

Rabbit, Fox, Tar — P.C. Verrone (Catapult)
When Baby appears in Original Hill, her name is on everyone’s lips. A young Black woman is a rare sight in this part of town, and she sits all day on the Foxes’ garden wall, swinging her bare feet and speaking to no one. That is, until the charismatic Lucius “Lucky” Foote comes along and touches her, sparking their romance. Arm-in-arm with Baby, who seems to exert a seemingly supernatural pull on the other residents, Lucky is confident he will secure the open city council seat away from Baby’s uncle Eugene Fox, the back-from-retirement white incumbent. With protestors reopening old wounds around the Black neighborhood that was leveled by the nearby highway decades ago and Lucky threatening his position, Fox believes it’s not just a city council seat at stake, but the “soul” of Original Hill.

The Jellyfish Problem — Tessa Yang (Berkley)
Dr. Jo Ness prefers jellyfish to people. Her best friend, Aldo, was the exception, but he died seven months ago. So she spends her days hidden away at an underfunded aquarium with her specimens and a draft of the jellyfish guide she and Aldo had been working on together. His voice is alive in the notes in the margins, and it’s enough. Almost. Until she receives a call from Nadia, one of the few other humans she’s loved but whom she hasn’t heard from in years, asking for her help. Nadia tells her a grand tale of a giant jellyfish terrorizing her tiny island off the coast of Maine and sends a grainy video of the creature. Frankly, the footage looks fake, but Jo drops everything to fly across the country to see Nadia again, and to find this supposed sea beast. She couldn’t save Aldo, but perhaps she can help Nadia. But when Jo arrives on Shattering Point, Nadia is nowhere to be found, and the islanders she meets each have something different to say about the creature they’ve dubbed Clementine… a jellyfish who changes all who see it.

June 9

Rasputin Swims the Potomac — Ben Fountain (Flatiron Books)
Reporter Clarence Thomas Jr. is looking for a great story, former country music teen star Faith Spack has parlayed her fame into a job at the White House, and the two-term incumbent president is campaigning for a constitutionally dubious third term. After an outbreak at a campaign rally, a mysterious new pandemic of “weeping sickness” sweeps the nation, threatening the president’s hold on the Oval Office. Desperate to retain power, he enlists the mystical pro wrestler Rasputin to help ensure his reelection and guarantee additional seasons of his presidential reality TV show, The Real West Wing. But as Rasputin’s appeal threatens to exceed the president’s, and the wrestler’s supposedly supernatural powers start to seem like the real thing, the campaign finds itself trapped in a spandex-clad destiny no number of executive orders can control, one in which both Clarence and Faith are compelled to play increasingly large parts.

We Hexed the Moon — Mollyhall Seeley (Saga Press—Indie conversion)
It is the summer after high school graduation, and four island-grown best friends are about to be forced apart by their Plans for the Future. Rather than process the world of expectations bearing down on them or the secrets they’ve kept hidden even from one another, they perform a ritual on the moon in an impulsive fit of teen bravado. They don’t expect it to actually work. But suddenly the moon is gone from the sky and at their sleepover, and she’s not interested in going back where she came from. As the balmy August night unfolds, the girls scramble to find a human sacrifice to replace the moon before their world is plunged into chaos.

Ring Shout On Saturn — Sheree Renée Thomas (Third Man Books)
Sheree Renée Thomas’s electrifying collection transports readers on a cosmic journey where ancient African Diasporic wisdom meets expansive Afrofuturist visions. From a prophet building a starship from salvaged dreams on a Martian farm to children breaking generational curses through powerful moonsongs, these tales explore themes of transformation, survival, and the enduring quest for liberation. Alien sisters navigate human complexities and river spirits offer profound wisdom, all set to an ancient beat that transcends time and space. Pulsing with Hoodoo, music, and myth, this collection resonates with the profound rhythms of existence, proving that true freedom knows no bounds—not even the cold void of space.

June 16

Heaven’s Graveyard — Grace Curtis (DAW)
Cod became an archaeologist to chase the ghost of her hero, Aleya Ana-Ulai. History may have written Aleya off as a myth, but Cod is determined to prove she existed, even if it means sifting through relics for the rest of her life. Then a message arrives summoning her home. Cod’s former teacher has found something monumental: the ruins of an enchanted city, slumbering beneath the soil. This could be the breakthrough they’ve always dreamed of. But with war brewing, rival powers circling, and ancient magics stirring underfoot, their discovery soon becomes far more trouble than it’s worth. Even Cod starts to wonder if some things are better left buried…

The Grief Shop and Other Stories from a Broken World — Alex DiFrancesco (Seven Stories Press)
The Grief Shop and Other Stories from a Broken World takes place after “the tragedy” transforms everyone into unfeeling people. At the center of the book is Gemma, who must cope with attempting to feel in light of the numbness. She works a series of jobs—at a grief-infused coffee shop, a boxing gym for pain therapy, a graveyard, and more—encountering a range of eccentric characters struggling to survive in a world where grief, ecstasy, suffering, and joy are commodities for some to purchase and for others to exploit. Gemma’s path is one of glimmering possibilities, ones with feelings she may not understand or accept.

Murder at the Spirit Lounge (Nora Breen Investigates #2) — Jess Kidd (Atria Books)
When Dolores Chimes, a famous medium, arrives in Gore-on-Sea, even surly Detective Inspector Rideout is lured in by her promises of messages for the afterlife. But after a reading goes disastrously wrong, Dolores loses her life—and the six sitters at the séance with her fall victim to supernatural deaths themselves in the days following the nightmare of a reading. Determined to unveil the truth, Nora finds herself chasing a ghostly serial killer she believes to be responsible, before the sixth victim—Detective Rideout himself—perishes along with the others.

June 23

Retro — Jessica M. Goldstein (Ballantine Books)
When Ash spots an ad for Retro during a depressing Instagram scroll—she’s in debt and unemployed; everyone else is, evidently, thriving—she’s surprised the algorithm sent it her way. She’s heard of recreational time travel, but it’s way out of her budget. Then she sees the caption: Come away with us! We’re hiring. So begins Ash’s life as a Time Travel Agent, leading wealthy tourists on vacations to historical hotspots. She takes bachelorette parties to live out their cowboy-romance fantasies in the Old West; she chaperones “’20s for your twenties” birthday excursions to speakeasies; she smiles politely as rich Wall Street guys give prospecting a shot during the Gold Rush. It’s all thrilling, outrageous, and totally surreal. Bygone America is just a Retro Metro ride away. Despite Ash’s tendency toward cynicism, she finds herself swept up in her dazzling new job. Sure, Ash isn’t the actress she’d always dreamed she’d be. But isn’t this so much better? It’s like Ash’s life is a movie, complete with an impossible love triangle. How is she supposed to choose between her mysterious office crush and the handsome private eye pursuing her in 1937? For the first time in years, Ash’s life feels enviable—so she’d really rather not pay attention to the strange things happening to her memory and relationships outside Retro. But as her trips threaten to unravel her real life, she confronts an unsettling truth: Escaping into the past was never really an escape at all.

The Door in Penrose Forest — Sean David Robinson (Crooked Lane Books)
As a boy, Nico once accompanied his mother on a research trip to investigate a stalled migration of monarch butterflies. One night, upon hearing her sneak out of their rented cabin, he followed her to a clearing in the forest where a famed mansion once stood. Paralyzed with fear, he watched his mother climb a staircase and vanish, along with the stairs and the strange glowing door at its peak. No one believed his story, and as he grew older, he too stopped believing it was real. As an adult, Nico returns to his hometown to care for his ailing father. But something strange is happening to the town. There are unexplained power fluctuations, people are going missing, and, reportedly, phantoms are roaming the woods. When Nico finds his mother’s field journal from the week she disappeared, including her account of the vanishing staircase, he begins to pick apart the mystery. All the tangled strings trail back to the same starting point: the Gilded Age family whose mansion burned down under mysterious circumstances in those very same woods where his mother vanished.

Animal Spiral — Luis Othoniel Rosa, translated by Katie Marya (Charco Press)
Middle-aged streamer twins in Bayamón, Puerto Rico, are the first human beings to successfully connect—sharing their consciousness across 34 translucent cables. In that moment, the Animal is born, an intracerebral force that quickly grows to encompass anthills of synaptically entwined bodies, a floating library kitchen redolent of rice and beans far above the Mississippi river, and a transhuman compound in a future Cuba on the Isle of Youth. Circling back and forth and ever progressing, Animal Spiral moves through 400 years of human, and then post-human history, beginning with a revolution on the streets of San Juan and ending with five brilliant siblings: the Squash (humanoid), Calima (beetles), Yemayá (eels), Coatlicue (serpents), and Juracán (anthropomorphic birds), who have millions of bodies and all the world’s intelligence, but only want to no longer be alone. This is a buoyant, joyous ode to possibility, a warning about the dangers of neglecting what makes us human, and an astonishing exercise of the flexibility and capacity of liminal spaces. Loneliness is a collective disease! We defend our right to madness! Brave are not the ones who resist; brave are the ones who let go!

Green City Wars — Adrian Tchaikovsky (Tor Books)
Meet Skotch. Raccoon, PI—yours for a few buttons as long as the job isn’t too illegal, whatever that means. A mouse has gone missing. Normally this wouldn’t raise any hackles, nor any alarms, but this mouse has something that everyone seems to want, though nobody appears particularly eager to say what that something is. The fee is good—perhaps too goodCertainly not something Skotch can easily turn down. If only Skotch can work out where the mouse is hiding, what he’s hiding, and why his secrets are upsetting a lot of animals caught up in the Green City wars.

June 30

Devotions — Lucy Caldwell (Faber & Faber)
A young Belfast theatre troupe brings their experimental production of Hamlet to New York. On a night-flight, travelling with a violin older than the United States, a professional musician slips through time. A man who loses all he thought he had, and finds himself haunted by all he never will, comes to a painful new understanding of what it might mean to love. Transporting and profound, these are stories of love, grief, longing, of new beginnings, and the ways we find shelter in each other.

Red X — David Demchuk (Hell’s Hundred)
In 1984, a young gay man vanishes without a trace, leaving behind a community of friends and lovers desperate for answers. Instead, they face everything from casual indifference to outright prejudice. As decades pass, more men vanish, revealing a terrifying, centuries-old demonic presence at the heart of the disappearances. Interspersed throughout, the author shares autobiographical vignettes: his earliest brushes with death and fear, his observations on queer culture and the horror genre, on representation and erasure, culminating in an elegiac and brilliantly woven narrative that blends fact and fiction.

Moss’d in Space (Moss’d in Space #1) — Rebecca Thorne (Bramble)
Torian Razner finally bought a starship, and contrary to Amelia’s assessment, it was not “a meteoric sign of stupidity.” Sure, the alien starship may have been abandoned for a century, and it may be covered in moss now… but it’s Torian’s ticket to freedom, regardless of what her ex… ah, captain… said. Except Torian’s first flight reveals a surprise passenger: the moss is actually an organic computer with a snarky attitude and serious abandonment issues. The target of its loathing? The immortal alien who built it (and then parked the starship, with Moss inside, and forgot about it). The same alien who just found Torian and accused her of “stealing” the ship. It’s entirely possible that Amelia was right about this meteoric stupidity.
