My Favorite Witch

Description for MY FAVORITE WITCH by Lisa Plumley:

Dayna Sterling's always been betwixt and between. Born in a desert town populated by witches and blissfully ignorant humans, Dayna had magic, but no clue how to handle it. So she left to forge a workaday life among ordinary Joes. Which is fine, really -- until the day one most extraordinary Joe turns everything upside down...

The assignment is simple. Trace the runaway witch; bring her home for compulsory "cusping" training. So why does Dayna set T.J. McAllister's half-warlock blood buzzing? Maybe it's the bonding spell that spontaneously connects them. Or the fact that T.J.'s powers go wonky whenever he's around Dayna. In any case, the attraction is making it damn hard for T.J. to accomplish his most important mission: prevent a dangerous uprising by locating a powerful witch prophesied to help him. She could be anywhere. She could be closer than he thinks...
