His Rodeo Sweetheart (Three Brothers Ranch Book 2)

LOST AND FOUND 

After serving in the Army, veterinarian Ethan McCall isn't sure where he belongs. So visiting Claire Reynolds's family ranch to help with her military dog rescue seems as good a place as any. Except that he can't stop thinking about the beautiful single mom. Ethan's happy to lend Claire a hand, but he can't offer his heart, as well. As far as he's concerned, it's damaged goods anyway. 

Claire recognizes the pain in Ethan's green eyes. With a son to raise, there's no room in her life for romance…or so she tells herself. But Claire and Ethan can't deny their attraction forever. Can two broken hearts come together to make a family whole? Or will Claire and Ethan continue to run from the thing that scares them most?
