"A strikingly original work of speculative fiction that brilliantly uses an audacious conceit—that immigration literally splits a person into two separate “instances” of themselves, one who moves to their new home and one who stays behind... A sharp, deeply felt first outing from a writer already at the top of her game." —Publishers Weekly Title Award Category Result Ref
