Note to self: getting left at the altar sucks.Double note: rebounding with your brother's best friend? A whole new level of disaster.Cooper Moore has always been the off-limits fantasy-gorgeous, filthy rich, and incapable of commitment. The one man I was never allowed to touch. My brother's ride-or-die.But when I catch my fiancé cheating an hour before our vows, I run. Straight to New York. Straight into Cooper's arms.It was supposed to be a fling. A rebound. A way to forget. Instead, every stolen glance and reckless kiss makes me wonder if forever has been waiting in his penthouse all along.The problem? Secrets never stay secret.And if my brother finds out, loving Cooper won't just break the rules.It could break us both.
