Earth’s attempt to colonize Mars meets with sabotage.

If all goes to plan, Officer Gold and her crewmates, Captain Blake and Officer Kang, will be the first humans “to live and die on a planet other than Earth.” After a lengthy “extend-sleep” aboard the Valiant, the shipmates are nearing Mars, where three robots have spent years assembling the mission’s base, dubbed Citadel. Those same robots are supposed to help the Valiant’s landing pod touch down smoothly and in the correct location, but when the time comes, Blake’s radio calls go unanswered. The crew executes a harrowing manual descent, only to discover that something has destroyed Citadel’s lab. Worse, their access codes don’t work on any of Citadel’s doors, and their suits are low on oxygen. Desperate pounding summons a badly damaged Robot Two, who lets them in and then retrieves Robot One from “her” hiding place. It seems all three robots have gendered (and named) themselves during their stint on Mars, in addition to pondering the meaning of life, the nature of death, and the existence of God. Unequipped for coping with such thoughts, Robot Three, aka Alex, went mad, forcing Robot One (Shay) and Robot Two (Wes) to exile him from Citadel. Wes asserts that the damage was Alex’s doing, but Shay believes an alien is responsible and intends further harm. Regardless, something clearly wants to kill them, and returning home isn’t an option. Straddling the line between horror, science fiction, and locked-room mystery, this posthumously published novel from the pseudonymous Coile is lean, mean, and propulsively paced. Although Coile’s characters are hastily sketched and a few of the tale’s more bizarre twists falter under scrutiny, Gold’s terse first-person narration and the claustrophobic setting conspire to amplify the high-stakes plot’s inherent tension.

Nerve-shredding space whodunnitry with a side of existential dread.
