Inferno’s Shadow (Artillerymen #4) — Taylor Anderson (Ace)
Colonel Lewis Cayce and his forces were a group of American soldiers bound to fight in the Mexican-American War—until they were stranded in a strange new world inhabited by vicious monsters, new friends, and deadly foes. Now Cayce has brought his army of displaced Americans and their indigenous allies into the heart of the loathsome, blood-drenched Dominion’s stronghold. If he can take the enemy’s holiest city and support the elevation of a new “Supreme Holiness” who seeks to moderate the Dominion’s thirst for expansion, slavery, and blood sacrifice, Cayce’s own goal for his army and new people to live in security and freedom will be assured. But no matter how good of a soldier he is, Cayce is ruled by reason, and the madness and seemingly suicidal treachery of his adversaries, not to mention the sheer titanic scope of the force arrayed against him, might finally be more than he can cope with. Which side will ultimately discover that even victory can end in defeat?

Infinite Archive (Midsolar Murders #3) — Mur Lafferty (Ace)
Mallory Viridian has had a quiet few months. Even with the increased influx of humans visiting Station Eternity, she hasn’t seen so much as a bar brawl. Used to people dying left and right around her, the lack of murders to solve has left her unexpectedly… bored. But humanity’s favorite way to waste time is on its way to her sector of the galaxy. A giant, one-of-a-kind data ship called Metis is bringing the entire Internet from Earth—as well as a mystery fan convention. On top of that, Mallory’s literary agent is aboard, and he tells Mallory that she’s the keynote speaker. It’s almost a relief when a killer decides to strike at the convention. When Mallory finds her agent dead, she knows she has to work fast to find the murderer. With a strange new alien with unknown motives, a ship with impossible abilities, a lonely living, comprehensive Internet, and a deadly crime to solve, Mallory has her work cut out for her

The Presence Malign (Deep Man #3) — Michael Mersault (Baen)
The heavy cruiser Salahdiin is the most powerful private warship in the history of the Myriad Worlds, and bears a Letter of Marque, the Imperial charter for legalized piracy. As the most successful fighting captain of the Imperial Fleet, Saef Sinclair-Maru is the ideal choice to command the privateer, but exchanging egotistical admirals for demanding shareholders carries its own unique challenges, particularly when the fate of humanity lies in the balance. While war rages within the Imperium, few comprehend the inhuman instigators at the heart of the conflict or their genocidal ambitions, but Saef and his counterpart, Inga, draw a surprising coterie of allies to their campaign of desperate resistance, including spy master Winter Yung, former Molo Ranger Kyle Whiteside, and even Erik Sturmsohn, a Thorsworld war chieftain sworn to overthrow the emperor. Together, in the face of approaching annihilation, they each must choose: Obedience to the edicts of their leaders, or loyalty to a deeper motivation that defines the very heart of humanity.

The Winds of Fate (Make the Darkness Light #2) — S.M. Stirling (Baen)
In a world where history can be rewritten at will, the threads of destiny intertwine in ways no one could have foreseen. Years after their groundbreaking journey into the past, Artorius and his team stumble upon a devastating revelation: the Chinese government has dispatched five time-travelers and a trove of advanced technology back to 165 CE, during the waning days of the Han dynasty. The team believed they were guiding Rome toward a new era of modernization and unity, but the emergence of Chinese influence threatens to unravel everything they have fought for. As whispers of innovation ripple through the ancient world, Artorius and his companions realize they are in a race against time—not just to protect their vision for a united future, but to prevent a catastrophic clash that could bring about nuclear war centuries sooner than they ever imagined. With their own presence now at risk of exposure, they must navigate the treacherous waters of politics, technology, and culture in a world caught between two colossal powers. As the balance of history teeters on a knife’s edge, loyalties will be tested, alliances forged, and the very fabric of fate will hang in the balance.

A Rebel’s History of Mars — Nadia Afifi (Flame Tree Press)
Kezza, an aerialist in the Martian circus, can never return to Earth—but she can assassinate the man she blames for her grim life on the red planet. Her murderous plans take an unexpected turn, however, when she uncovers a sinister secret. A thousand years into the future, Azad lives a safe but controlled life on the beautiful desert planet of Nabatea. His world is upended when he joins a crew of space-traveling historians seeking to learn the true reason that their ancestors left Mars. Separated by time and space, Kezza and Azad’s stories collide in the Martian desert.

The Immeasurable Heaven — Caspar Geon (Solaris)
The galaxy of Yokkun’s Depth has been settled since time immemorial. There is only one frontier left, and it’s a one-way journey: to pierce the skin of existence and delve the countless younger universes beneath. Running through these universes is the fabled Well, a fissure formed in the distant past into which horrors have been flung for millions of years. Amongst their number was an impossibly ancient sorcerer, cast down to the wastelands of a thousand apocalyptic worlds, never to return. Until now. Whirazomar is crossing the stars in the belly of a sentient spore, hoping she can make it to the Well before her masters’ rivals realise what she’s hunting: somewhere far below them, a hapless explorer has drafted a map of reality. A map that the exile is sure to seek out. A map so valuable that a kaleidoscope of beings will run the gauntlet of every universe to get it, even at the cost of their lives.

Ghost Cell (Ander Rade #2) — Zac Topping (Tor Books)
Ander Rade is doing his best to stay under the radar after the mess in Atlanta when he’s contacted by the Special Activities division for the Genetic Compliance Department. The mission: infiltrate a secret organization of rogue mods known as the Ghost Cell in order to find out what they’re doing and who they are doing it for. The catch: Rade’s old team leader, Sevrina Fox, is a member. But Rade’s been searching for her since his liberation from the fight pits, and he refuses to betray her now. So in exchange for his cooperation, the GCD agrees to extend their promise of an official pardon for his rogue status to her as well. As if gaining acceptance into the Ghost Cell isn’t challenging enough, Rade is forced to walk a tightrope between avoiding suspicion and minimizing collateral damage from the organization’s violent and unsanctioned operations. But as his investigation gains steam, he soon realizes that the Ghost Cell’s true ambitions are far more dangerous than anyone thinks, and that the time to act is running out. With powerful forces out to stop him, Rade must decide if there are limits to his loyalty to Sevrina, and whether that line has already been crossed, and above all, how far he’s willing to go for a pardon he’s not likely to live long enough to see.

Volatile Memory — Seth Haddon (Tordotcom Publishing)
With nothing but a limping ship and an outdated mask to her name, Wylla needs a big pay day. When the alert goes out that a lucrative piece of tech lies hidden on a nearby planet, she calls on all the swiftness of her prey-animal instincts to beat other hunters to it. What you found wasn’t your ticket out—it was my corpse wearing an AI mask. When you touched the mask, you heard my voice. A consciousness spinning through metal and circuits, a bodiless mind, spun to life in the HAWK’s temporary storage. I crystallized and realized: I was alive. Masks aren’t supposed to retain memory, much less identity, but the woman inside the MARK I HAWK is real, and she sees Wylla in a way no one ever has. Sees her, and doesn’t find her wanting or unwhole. Armed with military-grade tech and a lifetime of staying one step ahead of the hunters, Wylla and HAWK set off to get answers from the man who discarded HAWK once before: her ex-husband.
