Operation Day Care Highly skilled combat veteran and former rodeo star Rex Trainor likes to be in the thick of the action. So when he’s loaned out to Homeland Security, he plans to bide his time until he can get back to the real war. He doesn’t, however, plan on Sierra Daniels, a local day-care giver whose pretty smile hides a stubborn streak more daunting than Wyoming’s Beartooth Mountains. When tragedy nearly strikes the kids in Sierra’s care, Rex vows to expose the culprit. Rex hasn’t failed on a mission yet, and protecting the desirable Miss Daniels is no exception!
