One night. One bet. And now my world is turned upside down. Apparently, you're not supposed to fall for the rebound guy. Guess I didn't get the memo, because the first man I jump into bed with happens to be the one who sparks a flame in my heart. With his rakish charm and Irish accent, he steals my sanity and inhibitions. It's not long before I'm dreaming of something more than a quick fling. There's just one problem: Griffin Gallagher happens to be the one man my brother despises.
