No Getting Over You (Hometown Hearts #1)
Annie Dobbs, Edith Gracie

Uncertain and confused, she goes home to think and runs straight into Matthew Shaw, the one man she probably should avoid.

Katy has to admit she loves him every bit as much now as the day she'd left Vine Falls...but how could Matthew possibly still love her?
