Tessa Young is an 18 year old college student with a simple life, excellent grades, and a sweet boyfriend. She always has things planned out ahead of time, until she meets a rude boy named Hardin, with too many tattoos and piercings who shatters her plans.

Cassandra Smith is just another average teen: not too smart, not too popular, and definitely not pretty enough. But when Cassie's ordinary life at Jefferson High turns upside down when she bumps into the most popular guy in school, Liam. It's love at first sight. The only problem is that Liam is dating the Queen Bee of Jefferson High, Brittany. From mean girl drama to failing academics, Cassie still has a long way to go before she gets out of this un-average mess.
