They were best friends once. Now, Mia Carter and Ethan Hayes can barely stand each other. Five years after Mia left without saying goodbye, she returns to find that the boy she once knew is gone. Ethan hasn't forgiven her for leaving, and Mia isn't ready to tell him the real reason she did. But when they're forced to spend more time together, old memories begin resurfacing, along with feelings neither of them wants to admit. Maybe hatred isn't the opposite of love. Maybe sometimes, the person you should hate is the one person you've never stopped loving.
