There are no monsters anymore, or so the children in the city of Lucille are taught. Jam and her best friend, Redemption, have grown up with this lesson all their life. But when Jam meets Pet, a creature made of horns and colors and claws, who emerges from one of her mother's paintings and a drop of Jam's blood, she must reconsider what she's been told. Pet has come to hunt a monster, and the shadow of something grim lurks in Redemption's house. Jam must fight not only to protect her best friend, but also to uncover the truth, and the answer to the question--How do you save the world from monsters if no one will admit they exist?
