"A gripping, vivid magical action adventure." Louie Stowell, author of Loki
"Phenomenal!" Sophie Anderson, author of The House With Chicken Legs

Ancient magic and all-new heroes in a battle between the living and the dead - an epic story of chaos, myth and adventure for fans of Percy Jackson, from the author of The Boy to Beat the Gods.

When her island home is overrun by evil spirits, Evie is saved only by the powerful gemstone her parents entrusted to her. Her best friend Arthur is not so lucky - caught in the magical crossfire, he finds himself in the body of a cat.

On a mission to return him to his body and defeat the ghouls, Evie and Arthur team up with Cai, a trainee shaman, who helps them discover the truth. The terrifying Blackheart Man is plotting to steal the island's four magical gemstones and use their power to destroy the barrier between the worlds of the living and the dead. It will take all of Evie's magic, Cai's bravery and Arthur's talent for thievery to stop him.
