Two months shy of walking down the aisle, Amy Harrington can't imagine why she's suddenly having fantasies about other men. Sure, her sex life has become, well, routine, and she's never felt more confused about her future. Is this what saying "I do" is all about?
If she asked her best friends, Caitlyn and Leah, they'd say she was suffering from a potent mixture of chronic good girl syndrome and sexual code blue. Now, Amy can't help but think that maybe it's time she call off her wedding and embrace her inner bad girl. After all, brilliant and beautiful Caitlyn is clearly at peace with her naughty side, and nature girl Leah is so obsessed with her job she doesn't even need a man. Little does Amy realize that things aren't exactly perfect for her two best friends either.
Before anything gets too topsy turvy, Amy, Caitlyn, and Leah head off to a gorgeous spa in Mexico, where they plan to bond, get in touch with nature, and transform themselves into sexy, skinny vixens. What they don't realize is that this last hurrah could signal an exciting new beginning for each of them. . .
