Ethan Robinson, the sexiest professor on campus, has fallen hard for mysterious Dakota Faraday. He knows what he wants: an exclusive relationship. But Ethan fears the pretty, twentysomething part-time college student may be secretly involved with another man. And just when he's about ready to give up on her committing, she surprises him...in the most revealing of moments. Persia King's sultry voice makes her irresistible to her clients at License To Thrill, a phone-sex line. It is just a job to her, until she falls for one of her late-night callers...and he seems to return the feeling. Ethan's never laid eyes on sweet, sexy Persia, but she's arousing a lot more than his libido. This is one Ph.D. research project he's thrilled to be working on...and now he's got two vibrant women vying for his heart. But how can he choose between Persia and Dakota? Love's calling...and it may be destiny on the other end.
