The Mediator (Unabridged‪)‬

That Kerry's birthday falls on the most romantic day of the year sucks. That she's set up on a date with both an angel and a demon sucks worse. But she's about to discover that being trapped between good and evil makes for one hell of a good time.

Mike and Cal, angel and demon, are reluctant business partners. To help them get along, Cupid sends a mediator called Kerry, but rather than working on a truce, the guys are soon locked in a different battle, this time over Kerry's smoking curves.
