Forty-one hours of silence. Forty-one survivors. Not one of them can say why.When the fast-attack submarine USS Manta stops answering four hundred miles under the Arctic ice, the Navy sends her sister boat expecting a graveyard. Lieutenant Commander Maya Reyes leads the boarding party braced for hull damage, casualties, an explanation. What she finds instead is a crew standing in spotless compartments, logs current, checklists completed past the point anyone would bother - alive, uninjured, and answering every question in the same unhurried, agreeable warmth, half a beat out of sync with each other.Reyes has one job: get her people home before the next transmission window closes and an admiral topside decides the recovery isn't worth the risk. But the longer she interviews Manta's survivors, the less certain she becomes that anyone left aboard is actually the one answering - until two sailors respond to the same question in the same instant, word for word, and Reyes understands she isn't running a rescue anymore. She's negotiating with something that used to be forty-one people, and has no intention of being separated from any of them.With a foreign submarine closing on the same ridge line and an admiral topside more interested in containment than in casualties, Reyes has hours - not days - to decide how many of the people she came for she can still call people, how much of her own crew she's willing to spend finding out, and whether "bringing everyone home" was ever a promise a submarine could actually keep.FULL COMPLEMENT is a claustrophobic submarine thriller for readers of The Thing and Annihilation, where the discipline that's supposed to save you - obey the order, trust the man next to you, never break formation - turns out to be exactly what's hunting you. The crew of the Manta didn't go quiet.They never stopped answering.
