Samara is one of the Knowing, and the Knowing do not forget. Hidden deep in the comfort and splendour 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 Earths 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 has 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?
