Finbar and Molly were childhood best friends. They live next door to each other and spent hours and hours together. Until they didn't.

Now 18, Fin and Molly move in very different circles. Molly is popular, pretty, dating the most handsome boy in the whole school. Fin has one friend and he's pretty sure he hates his dad and his little sister.

At a party one night, though, they're pulled together in a way neither of them expects and then follows a life-changing year that will see them experiencing friendship and love an everything in between.
