Imagination is a powerful thing… There are three things in this world that seventeen-year-old Rémy would guard with his life: his gold pendant, his blues harmonica, and his mother’s journal. This is all he has left of his murdered family. And he believes these objects will lead him to their killers. But he can’t hunt them down alone. He needs Matt and Em Calder, twins who can bring art to life and travel through paintings. For, like them, Rémy has supernatural powers. He is a Conjuror, descendant of an ancient bloodline that can change reality with music. Together, Rémy, Matt and Em must race through history, facing the terror of the Inquisition and the horror of the slave trade before they can uncover the truth. But evil forces are rising in the world. Will the final battle save them or destroy them?
