Lila Monroe has loved her best friend's older brother for years. Rowan Pierce never noticed. He was always off-limits. Always untouchable. Always someone she watched from the sidelines-quietly, hopelessly. Then one stupid game turns into one reckless bet. Rowan is dared to get her into his bed by the end of the month. What no one knows? Lila has never been with anyone. What Rowan doesn't expect? To finally see the girl he's been overlooking-and to realize too late that this bet might cost him everything. Because some bets aren't meant to be won. And some hearts don't survive the truth.
