One week. Manhattan apartment. Super hot ex-boyfriend. What's the worst that could happen? It's been nine months since Caitlin Parker has seen or heard anything about Martin Sandecki, nine months and five significant milestones. She survived the severe disappointment of her first love, becoming stronger (hiding in closets less often) than ever before. But now Martin is back. And he wants to be her friend. But he's sending mixed signals to the Bunsen burner in Caitlin's panties. Will Martin be able to capture Caitlin's heart again? Can Caitlin and Martin be just friends? Or, despite the abundance of chemistry, some bonds are too volatile to withstand it?
