The Reluctant Witch Series Book Four: Teddy

Teddy Stewart's life is better than okay. Her Ph. D in hand, she's landed her ideal job as assistant dean at a prestigious college and met a new colleague who is handsome, interesting and, sadly, a pain in her pretty behind. Like her sisters -all three witches- Teddy is about to find out that good magic can turn bad in the blink of an eye when Sabine, a long-lost aunt and a practitioner of dark magic materializes on her doorstep.
A master of chaos and destruction, Sabine is determined to steal the powers of Teddy and her sisters and become the most powerful dark sorceress of all times. To protect her family and friends, Teddy must dig deep and conjure up her most valuable power - courage!
