1. Don’t sleep around. 2. Don’t kiss and tell. 3. Be nice. 4. Don’t text or call. 5. Don’t fall in love.   The rules were simple...until they weren't.   I have everything I ever thought I could want: a nice home, a job I love, two beautiful girls, and my husband, Gabe - my high school sweetheart who still rocks my world. If you ask anyone to describe me they would say, "Oh, Mirella? She's such a nice girl." And that’s true...until a mysterious, peculiar man and his beautiful wife enter our lives.   Weston and Bridget Hanson are no ordinary couple—they’re stunning, enigmatic, and sexy as hell. During the course of one unexpected evening, my ordinary world is turned upside down. How could it not be when Weston and Bridget propose the unthinkable? And when the unthinkable is so very tempting, giving in becomes inevitable.   It sounds so logical and simple. Just five rules and we can all have what we desire. But the heart doesn't follow rules, and now passion, jealousy, and confusion threaten to tear everything apart.   Two beautiful couples. Five simple rules. One hot mess.
