A gateway is opened. A portal to Hell, hidden beneath a great tree in the tiny swamp-town of Greenville. But these swamps hold more secrets than even the superstitious townspeople can imagine. Lucifer has grown restless in Hell, bored with a life of giving and receiving pain. But one of his generals has devised a way for their kind to be free. The catch: they must live among humans, AS humans. But he'll pay anything to be free. Even if it means growing a soul. Elle MacIntosh is just starting her second year at Greenville's tiny university. Never having left her hometown, she yearns for anything outside the ordinary. But when she and her friends visit the locally famous Devil's Oak-- a tree rumored to be a hotspot for demons, witchcraft, and hauntings-- she realizes a boring life wouldn't have been so bad. Now, she's scared. She's being hunted by monsters. And she's the sweetest thing Lucifer has ever seen.
