The year is 1873, and a bison hunter named Samson travels the Kansas plains, full of hope for his new country. The year is 1975, and an adolescent girl named Bea walks those very same plains; pregnant, mute, and raised in extreme seclusion, she lands in an institution, where a well-meaning psychiatrist struggles to decipher the pictures she draws of her past. The year is 2027 and, after a series of devastating storms, a tenacious engineer named Paul has left behind his banal suburban existence to build a floating city above the drowned streets that were once New Orleans. There with his poet daughter he rules over a society of dreamers and vagabonds who salvage vintage dresses, ferment rotgut wine out of fruit, paint murals on the ceiling of the Superdome, and try to write the story of their existence. The year is 2073, and Moon has heard only stories of the blue planet—Earth, as they once called it, now succumbed entirely to water. Now that Moon has come of age, she could become a mother if she wanted to–if only she understood what a mother is. Alone on Mars with her two alien uncles, she must decide whether to continue her family line and repopulate humanity on a new planet.
