Stranded on the deserted island of Mortiferum, the wizards and the demigods must join together in order to survive. Forced to face their greatest fears, the groups will have to face the greatest challenge of all - working together. Disclaimer: I do not own any of the characters (except for Acacia and Mark) or their worlds. They belong to J.K. Rowling and Rick Riordan. I don't own the cover.
