An unfamiliar witch who calls herself the Red Queen has captured Sylus. Phoebe must beat her at chess to get him back. Each chess square contains a hidden challenge, an opponent Phoebe must defeat. One loss, and the Red Queen keeps Sylus. Phoebe faces the challenges as Sylus looks on, unable to free himself or her, cheering her on as she faces the most challenging opponents of her career, until at last she must face the most formidable enemy she has ever battled. If she cannot hold on, it's checkmate Phoebe...but she never promised the Red Queen that her team wouldn't keep fighting if she loses.
