"Wedding planner Karen Petersham loves weddings--usually. Her new client, Sophy, has brought along her best man for advice. And the best man is none other than Karen's sexy ex-husband, Dexter Crane. But there are rules when engaging in ex-sex: 1) Do not get romantically involved (obviously) 2) All fun. No fight. 3) Two words--booty call! 4) (Reminder: nix the romantic involvement) 5) Remember why it ended (important!) 6: And get out before you fall in love again"--Publisher.
