You know those love songs that chorus, Only You? My jam is, Anyone But Him. And guess who recently rolled into town? The guy who ditched me in high school and there's no avoiding him. When my grandmother strikes with her classic question about if I have a boyfriend yet, I want to dodge the family disappointment drama saga and say, No Way, but I can't let her downand he owes me.

After over a decade in the military, I'm back in my hometown to help my sister while her husband is deployed. A brother helping another and all that. I didn't imagine the fiercely independent motorcycle-riding surfer girl from high school would still be here and be more beautiful than ever. When she asks me to be her fake boyfriend, I don't decline because it means righting a wrong.
