Until one day someone knocked into her, it wasn't until later that night she found out who he was...
Zac, her teenage crush! Well, more like the love of her life. And he was back. Hallie knew she would need to speak to him. She had so many questions about why he just up and left ten years ago.
Will she talk to him so she can move on or will they sort things out and bask in the love of years passed?
