Two boys, alone in space. After the first settler on Titan trips her distress signal, neither remaining country on Earth can afford to scramble a rescue of its own, and so two sworn enemies are installed in the same spaceship. Ambrose wakes up on the Coordinated Endeavor, with no memory of a launch. There’s more that doesn’t add up: evidence indicates strangers have been on board, the ship’s operating system is voiced by his mother, and his handsome, brooding shipmate has barricaded himself away. Nothing will stop Ambrose from making his mission succeed, though—not when the settler he’s rescuing is his own sister. In order to survive the ship’s secrets, Ambrose and Kodiak will need to work together and learn to trust one another . . . especially once they discover that they are up against larger forces than they had ever considered. Love might be the only way to survive.
