Welcome to the Arcadia. Once a luxurious cruise ship, it is now home to the Stranded. For forty years, they have lived, and died, on the water. No one is allowed to disembark, ever. Esther is sixteen and a loyal citizen, working hard for the rare chance to live a life on land as a medic. But her plans are derailed when she saves the injured Nik, a rebel intent on a dangerous strategy to liberate the Arcadia. Both are willing to risk everything to reach dry land but as they become more involved in the rebel cause, they find themselves at the crux of a revolution where their choices will decide the fate of everyone on board.
