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? At once thought-provoking and utterly thrilling, this extraordinary companion novel to Sharon Cameron's #1 New York Times bestselling The Forgetting explores the truth and loss that lie within memory, and the bonds that hold us together.
