Destroyer by Brian G Turner

SPSFC

Hugh Howey's SPSFC semi-finals winner: "A solid piece of space opera. The confines of a spaceship made for a tense setting, and the strong characterisation and well-handled plot twists made this a winner for our judges." Jaigar expected to wake up after thirty years to start building a new world in another star system. Instead, he finds himself one of a handful of survivors on an abandoned colony ship. With no food or water, and only emergency power, his first challenge is to keep everyone alive. The next is to try and solve the mystery of their situation, by figuring out what happened to the original crew and other colonists. But Jaigar will find survival more difficult than he expects, especially when each of the other survivors has a secret that could help him - or kill him.
