Dawn : Lilith's Brood 1

When Lilith lyapo wakes in a small white room with no doors or windows, she remembers a devastating war, and a husband and child long lost to her. She finds herself living among the Oankali, a strange race who intervened in the fate of humanity hundreds of years before.

They spared those they could from the ruined Earth, and suspended them in a long, deep sleep. Over centuries, the Oankali learned from the past, cured disease and healed the world. Now they want Lilith to lead her people back home.

But salvation comes at a price - to restore humanity, it must be changed forever...
