Sharon Cameron returns to the rich world of The Forgetting with a companion novel as thrilling and intricately crafted as the first. Samara is one of the Knowing, and the Knowing do not forget. Hidden deep in the comfort and splendor of her underground city, a refuge from the menace of a coming Earth, Samara learns what she should have never known and creates a memory so terrible she cannot live with it. So she flees, to Canaan, the lost city of her ancestors, to Forget. Beckett has flown through the stars to find a dream: Canaan, the most infamous social experiment of Earth's antiquity. Beckett finds Samara in the ruins of the lost city, and uncovers so much more than he ever bargained for -- a challenge to all he's ever believed in or sworn to. When planets collide and memories clash, can Samara and Beckett save two worlds, and remember love in a place that has forgotten it?
