Three days before Erin Bellini's wedding, her fiancé breaks up with her--in an email! Hurt and embarrassed, she decides to have a fling with veterinarian Jason Callum, who's both the best man and the hottest guy she knows. But Jason wants a lot more than just a one-night stand with the woman he's cared about for years. So he's taking things slow. And hot. And showing Erin what real love can look like.

Suddenly Erin finds herself spending a lot more time with Jason than she intended. Feelings she never planned on having again are wrapping around her heart, refusing to let go. Erin isn't sure she can trust her instincts, though. After all, she made a terrible choice with her ex-fiancé. But Jason intends to convince her that he's the best man for her, and that what they have together is a real love that will last forever.
