Rochelle wakes from cryostasis to take up her role as engineer on the colony ark, Calypso. But she finds the ship has transformed into a forest, populated by the original crew?s descendants, who revere her like a saint. She travels the ship with the Calypso?s creator, the enigmatic Sigmund, and Catherine, a bioengineered marvel who can commune with the plants, uncovering a new history of humanity forged while she slept. She discovers a legacy of war between botanists and engineers. A war fought for the right to build a new Earth ? a technological paradise, or a new Eden in bloom, untouched by mankind?s past. And Rochelle, the last to wake, holds the balance of power in her hands.
