Meg's 12, and her friends are all gone for the summer. When 14-year-old Helena moves into the house down the street, Meg is intrigued but unnerved. Helena and her mom seem more than a little strange with their candle ceremonies, five-pointed star necklaces, talking to ghosts, and their bookstore that has books with odd titles like Teen Witch and White Magick. But Meg's desperate for a friend.

Shamar, Meg's guardian angel, has his work cut out for him, especially when he sees the yellow-green eyes of demons watching Meg, waiting for an opportunity to move in on his charge.
