As Penelope's magic continues to grow stronger with the coming high tide, she and Alexis will have to depend upon each other more than ever to keep everyone they care about safe from the continuing attacks by Thevetat’s priests. When the magical high tide finally peaks, the long-awaited battle against Thevetat will begin, and Penelope, Alexis, and the magicians will have to rely on both powers of old and new if they hope to defeat their enemy once and for all.
