Sins of the Flesh — Elizabeth Jewell

Alec Roth inherited a Devil's bargain from his family, and is now in possession of an Agrippa Book, which gives its owner everything he could ever imagine. But the price is steep, and after nearly losing his life to his excessive lifestyle, Alec is turning over a new leaf. He's buying a new restaurant without the help of the Book and its attendant demon, and he's even found new love with the lawyer who's helping him close the deal. But when she betrays him, will he be able to save them both from the grip of the Demonic Book?
