After what seems like a lifetime of following her father across the globe and through the centuries, Nix has finally taken the helm of their time-traveling ship. Her future—and the horizon—is bright. Until she learns she is destined to lose the one she loves. To end up like her father: alone, heartbroken. Unable to face losing Kashmir—best friend, thief, charmer extraordinaire—Nix sails her crew to a mythical utopia to meet a man who promises he can teach her how to manipulate time, to change history. But no place is perfect, not even paradise. And everything is constantly changing on this utopian island, including reality itself. If Nix can read the ever-shifting tides, perhaps she will finally harness her abilities. Perhaps she can control her destiny, too. Or perhaps her time will finally run out.
