Over the Moon — Liz Isaacson

A twin brother, a fiery veterinarian, and the mistaken identity that sparked a new romance... Caleb Chamberlain has spent the last five years recovering from a horrible breakup, his alcoholism that stemmed from it, and the car accident that left him hospitalized. He's finally on the right track in his life, and he's found peace with being a cowboy at Horseshoe Home Ranch for the rest of his life. Until Holly Gray, his twin brother's ex-fiance mistakes him for Nathan. Caleb wasn't around much when Nathan and Holly were an item, and it takes him a few minutes to figure out who she is, but definitely not that long to want to get to know her better. Holly's back in Gold Valley to get the required veterinarian hours to apply for her graduate program. When the herd at Horseshoe Home comes down with pneumonia, Caleb and Holly are forced to work together in close quarters. After checking with his brother, Caleb decides he wants to start something with Holly, despite her plans to leave town in eight months. Holly's over Nathan, but she hasn't forgiven him -- or the woman she believes broke up their relationship. As she and Caleb get to know one another better, she'll have to figure out if she's really in love with Caleb -- or the memory of Nathan -- and how to forgive everyone she hasn't. Can Caleb and Holly navigate such a rough past to find their happily-ever-after?
