Sol Voss wakes from cryosleep aboard Jericho, Earth’s last colony ship, carrying a precious fusion core and humanity's final hope. As the last ship Earth could afford to send, Jericho follows the faint, scattered trail of earlier vessels—most of which vanished without a trace. Only one colony, Haven, had managed to survive long enough to call for help. But they’re fading, their fusion core failing, and without it, Haven may be lost. To Sol, Jericho’s mission is simple: deliver the core and ensure humanity’s survival. Yet as she settles into the isolated, cavernous ship, she realizes her father, Dr. Julian Voss, has left her with more than just a mission. Strange changes start to manifest within her, memories of his experiments surface, and shadows seem to shift in the corners of her vision. And as Jericho drifts deeper into the darkness, Sol can’t shake the feeling that something else is on board—or that she herself may be more than she understands. On a voyage that will span centuries, Sol must come to terms with a legacy she barely understands and a future more uncertain than she ever imagined. Jericho is the last chance for Haven, but Sol begins to wonder if her father’s true goal was to deliver humanity—or transform it.
