Not the One by Toni Aleo

Genevieve Stone got her first taste of passion as a teenager on a road trip to Kentucky with the bastard bad boy of the country club. Everyone agreed he was not the one for a girl from her station in life.
Ten years later, she’s a successful romance novelist and is engaged to be married to the appropriate sort of man. But something is holding her back from finishing her latest book and from joyfully walking down the aisle. On impulse, she takes off for Spring Grove, the site of her youthful indiscretion and the location of most of her happiest times.

What she thought was just a short walk down memory lane quickly becomes much more as Gen reconnects with friends from her youth and is welcomed back into the quirky arms of small-town Kentucky. And it isn’t long before she starts to realize that the man who was supposedly so wrong is oh so right.
