Morgan is incredibly attracted to Cal, a new senior at her school, but so is her friend Bree. Cal invites both of them to what ends up being a Wicca ritual. Morgan is fascinated by Wicca, and some weird psychic events that happened to her after that night. But overshadowing her enthusiasm is a rivalry developing between her and Bree.
Very readable, with a strong plot. I wish the end hadn't been as abrupt - it's a total cliff-hanger. Not for those who object to the occult and magic, or for sexual themes.
