Hannah's about to start her senior year, and she's never been so scared. That's because she's going to have to face:
1. Sebastian: the guy who dumped her on the last day of junior year.
2. Noah: the guy she's totally fallen for.
3. Ava: Noah's girlfriend...and Hannah's best friend.
As Hannah tries to figure out how she got herself into this colossal mess, one thing becomes crystal clear: there's absolutely no way she's going to make it through this day in one piece.
