In a future America, a hijacked ship is the key to the fate of the world. To privileged Amelia, the lavish Grand Voyager is just another gilded cage. For Gabriel, a covert rebel operative, the luxury liner is his one chance at vengeance. But when terrorists storm the ship, Amelia and Gabriel are forced into an unlikely alliance. Hunted by ruthless killers, Gabriel is Amelia's only chance. But he needs her too, in ways he never expected. But nothing is as it seems. As the lines between enemies and allies blur, they uncover an even greater threat, more insidious than they ever imagined--and it's already on the ship. Now, they're thrust into a battle not just for their survival, but the very fate of the world. Life as they know it is about to end.
