Volume three of Tea's Chelsea trilogy finds her protagonist Sophie and her friend and mermaid mentor, Syrena, arrived at an ancient castle in a WWII-haunted Poland. There the teenager will have to use her magic powers to fulfill her destiny by battling her chain-smoking grandmother, Kishka, the embodiment of pure evil. To win, Sophie must remove sadness from the world om every person, the world over. A tall order, but perhaps she won't have to fight Kishka alone, for there are three other girls om she has seen in a vision o are like her. First, Sophie must train with the help of a nerdish boy named Tadeusz and a formidable witch called Jezda. Even with Sophie's preparations, Kishka is still more formidable. Will Sophie find the strength to defeat her? The trilogy's conclusion is sometimes more matter of fact than magic and the denouement is a bit anticlimactic, but the book ends with a sly wink that reminds the reader that evil is, perhaps, as eternal as goodness.
