Racing Hearts (Bennett Boys Ranch Book 3) Lauren Landish

I have not read the first two in this series, but after reading this one I will for sure now be reading them. The Bennett's and the Tannen families have fought for years. Not just because their land was next to each other, but because they couldn't stand each other. But than Shay is sitting at her favorite spot one night and a surprise visitor, Luke Bennett shows up and totally turns her life upside down. As the days go on and they meet up more often they both start to realize that no matter how much their families hate each other they are falling for each other. Now they have to find a way to make their families come to grips with their reality.
