“A locked-room mystery set in the near future…. A fast and riveting read.” —CrimeReads
“This sci-fi horror novel delivers a gripping blend of psychological tension and fast-paced suspense. Structured like a locked-room mystery, where the locked room is an uninhabitable planet, the story builds an atmosphere of isolation and paranoia. Jump scares and plot twists fuel the mounting sense of dread, though beneath the thrills, the narrative explores the evolution of artificial intelligence and the fine line between programming and thought.” —Library Journal
“Lean, mean, and propulsively paced…. Nerve-shredding space whodunnitry with a side of existential dread.” —Kirkus
“Curlicue plot twists and an Among Us vibe enhance[s] this space gothic from Coile (William)…. With its tough-as-nails heroine and scheming robots, there’s plenty here to hold sci-fi fans’ interest.” —Publishers Weekly
