The Most Likely Consequence of Contact: Revealing Seth Dickinson’s Exordia


Published on February 6, 2023

“Anna, I came to Earth tracking a very old story…”

Seth Dickinson explodes into a new genre with Exordia, the acclaimed fantasy author’s Crichton-on-acid science fiction debut arriving January 2024 from Tordotcom Publishing.

“Anna, I came to Earth tracking a very old story, a story that goes back to the dawn of time. it’s very unlikely that you’ll die right now. It wouldn’t be narratively complete.”

Anna Sinjari—refugee, survivor of genocide, disaffected office worker—has a close encounter that reveals universe-threatening stakes. While humanity reels from disaster, she must join a small team of civilians, soldiers, and scientists to investigate a mysterious broadcast and unknowable horror. If they can manage to face their own demons, they just might save the world.

Praise for Exordia

“Exordia is an avalanche: an inevitable, overwhelming, pell-mell landscape-scale transformation of a book. Dickinson uses science fiction as an ethical scalpel, and the results are breathtaking: viciously funny, vivid to the point of horror, and entirely profound.”—Arkady Martine, Hugo Award-winning author of A Memory Called Empire

“Exordia is a comprehensive taxonomy of violence at every level, from the subcellular to the intergalactic. . . . It’s an apocalyptic chanson de geste, with a dizzyingly fractured Round Table who experience damnation—not just spiritually but literally, formally, communally and visibly—as well as a comprehensive study of natural history, moral lessons, spiritual and cultural translation, and the hierarchy of all possible passions. There’s a deeply original spiritual order in this universe that sharpens the significance of every moment, and I found myself wrung out and exhilarated as I came unwillingly to the end of it.”—Daniel M. Lavery, author of The Merry Spinster

“A science fiction juggernaut.”—Tamsyn Muir, New York Times bestselling author of the Locked Tomb series

“Beautiful, introspective, and unbelievably tense. It feels like being in a hospital waiting room in the best and worse sense, the suspended moment right before you find out what’s going on.”—Cassandra Khaw, USA Today bestselling author of Nothing But Blackened Teeth

“Conceptually mind-blowing. Viscerally horrific. Hofstadter meets Lovecraft during a really bad acid trip, but better written.”—Peter Watts, Hugo Award winner
