Gil Valentine knows three things: he doesn't want kids, he doesn't want a relationship, and he likes to be alone.

He spends Sundays tinkering in the garage, cruising on his motorcycle, and enjoying the luxury of a bed that he doesn't have to share. After his last relationship with his best friend's brother ended in disaster and nearly cost him a friendship, Gil swore off anything that might lead to complications.

Rowan Verne knows two things: being a single dad is hard, and being a single dad to a pre-teen is harder.

After the death of his wife and a tough few years as a struggling single dad, he's determined to give his son a better life in a new town. Between moving into a fixer-upper and handling the demands of parenting a twelve-year-old, he's juggling more than he anticipated—and then his son turns up down the street, talking to a very handsome, and very single neighbor.

Rowan is everything Gil doesn't want, and Gil is everything Rowan doesn't think he needs. Even though they're opposites, the chemistry between them is undeniable. What's supposed to be a one-time thing quickly turns into something both men want to continue. And when tensions get high and memories from the past flare their ugly heads, Gil and Rowan realize everything has changed, but they both know one thing to be true.

Once is never enough.
