Now, connected by Gabriel and their colliding pasts, xie joins collapse survivor Annie and the enigmatic, charismatic Chance on a desperate cross-country race, carrying a disc of xir mother's vital plans, whose encrypted contents may be Parole's salvation. First they'll board the FireRunner, a ship full of familiar faces that now sails through Tartarus' poison storms. Together, they'll survive Tartarus' hazards, send a lifeline to lost Parole - and uncover the mystery connecting every one of them.The world outside Parole isn't the one they remember, and it didn't want them back. But they'll save it just the same. It's what heroes do.
