From the author of the New York Times bestselling Iscariot comes an award-winning novel that poses the question: if a demon came up to you and offered to tell his story, would you listen? Clay's life has reached a standstill. Recently divorced, he spends his days drifting from his drab apartment to his equally lackluster job as an editor for a small Boston press and back again. His dreary routine has left him mired in a seemingly meaningless existence, until the night he meets Lucian—a demon—and everything changes. With the simple words, "I'm going to tell you my story, and you're going to write it down and publish it," Lucian catapults Clay's mundane life into turmoil. What begins as an intriguing mystery soon spirals into a chaotic obsession as Clay struggles to piece together Lucian's dark tale of love, ambition, and grace—only to discover the demon's story is strikingly similar to his own. And the only thing that matters now is finding out how the story ends . . .
