When she was nine-years-old, Katie knew she wanted Chris to give her her first kiss. It wasn't because she was in love with him (no way, he was her best friend! Besides, she was in love with his fourteen-year-old big brother), it was because she could make him do anything she wanted.

Besides, it didn't really mean anything. After all, it was only a kiss.

But things started to change. They grew up. They parted ways and went to different high schools. Then other girls and other boys—well, just one particular boy—came into the picture, throwing their lives upside down.

Told from the alternating points of view of Katie and Chris, this love story between two best friends will tug at your heartstrings and leave you thinking about how the simplest things mean so much.
