Witches Rule

Jenna's a special witch, sort of, when her magic works, which it often doesn't. One of three remaining demon assassins, she and her sister witches, Roz and Colleen, are Earth's only hedge against being overrun by Hell's minions. On the heels of Roz's and Colleen's weddings, Jenna is headed for the U.K. when a demon confronts her. Any other witch could teleport out of the plane, but not her. Frustration about her limited power eats at her. It would be pathetic to get killed for lack of skills a teenager could master.
Startling truths surface about Jenna's magic, and then there's the problem that she's falling in love with two very different men. At first she believes she has to pick one of them, but her spirit refuses to walk away from either. It's impossible to choose between a seer with dreams in his eyes and a beautiful man who intuits her every need. Standing on the verge of Earth's destruction, will she defy convention and follow the song in her heart?
