The Return by Noelle Adams

Ria Phillips has a plan. Stay strong. Stay busy. Stay focused on what’s important. And don’t start daydreaming again about a certain pair of soulful brown eyes.

No, it won’t be easy. Jacob Worth was her first love. Her first time. Her first everything. Until he left town one day without explanation. He broke her heart back then, but she’s not a teenager with a crush anymore. She’s an adult–with a plan.
In the past eight years, Ria has built a good life for herself in her small hometown. She and her friends have used their creativity and business savvy to turn the little florist shop she inherited into an astonishing success. She’s got more than enough in her life to be proud of, and she’s going to make sure Jacob sees that.

She’s not going to let him rattle her. She’s not going to watch him from afar, even if he’s even hotter than before. And she’s definitely not going to fall into bed with him. Or, if she accidentally slips up, it will only be once.
She learned her lesson a long time ago, and she’s not going to fall for Jacob again.
