A little disaster, a lot of chemistry, and one night none of them will ever forget. Riley has been in love with her best friend’s older sister, Ella, for longer than she cares to admit. Unfortunately, Ella has always been completely off limits. Not only because she’s her best friend’s sister…but because Ella is already happily dating someone else. So, Riley does what she does best: buries the crush, pretends everything is fine, and shows up for the annual Fourth of July celebration determined to finally move on…until she meets Ella’s girlfriend, Quinn. Suddenly, Riley has a very inconvenient problem. She doesn’t just have a crush on one unavailable woman. She has a crush on two.
