Hell needs a new Devil. The universe chose the sweetest kid alive.
Philip is polite, honest, and kind—and absolutely the last person who should inherit the throne of Hell. But when a cosmic mistake sends him tumbling into the underworld, the dying Lucifer has no choice but to teach this painfully good-natured boy the art of wickedness.
Philip is terrible at being bad, but everything changes when he meets Satina, a clever and captivating she-devil who awakens feelings he never knew he carried. As he navigates the eerie, unpredictable underworld, Philip encounters both friends and foes—but who can he trust when he uncovers a conspiracy aimed at the dark throne?
