“As brilliant as it is bizarre. From the very first page you know you are in the hands of an author at the height of their abilities. . . . This is the unhinged cannibal book of my dreams—and my nightmares.” —Ava Reid, #1 New York Times bestselling author of A Study in Drowning

“Enthralling, weird, and brilliant. A medieval pseudo-historical horror tale that explores what happens when our prayers are answered but we’re not sure what has answered them, or what it will demand of us in return. There’s no other story like this, and I mean that in the best possible way.” —Christopher Buehlman, bestselling author of Between Two Fires

From the nationally bestselling author of The Luminous Dead and The Death of Jane Lawrence, a transfixing fever dream of medieval horror following three women in a besieged castle that descends ravenously into madness under the spell of mysterious, godlike visitors.
