There are many worlds...
Giovanna Lee is having lots of difficulty in her life. Her parents won't let her go to Disney World with the rest of her show choir, and the magic she wields as holder of a Twilight Gem is no longer working. But these problems will pale compared with what happens when she meets the Crime Syndicate... A small caution to readers: there are some scary scenes that might be too frightening for young children.
