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?
"An instant classic. Wonderful characters, exciting world building, and headlong adventures. An epic fantasy in the classic mould of Tolkien and Stroud. Highly recommended."
Eoin Colfer, author of the Artemis Fowl series
"Thrilling, fascinating, profound and still somehow funny all the way through. I loved this book and this world."
