Nestled in the sunny fields of Tennessee lies the McDaniel family’s Second Chance Ranch Animal Rescue. Two new arrivals are on their way, but only one is the four-legged kind. 
Staff Sergeant Mike Kowalski wants only one thing after he gets home from Iraq: to sleep in a king-sized bed with clean sheets. But first, he has to hand off his fallen commander’s dog, Trooper, to his family without handing off his heart to Sierra…
 
Sierra McDaniel needs a break. Her family life is crazy, and when she’s not mucking out kennels, she’s slogging through grad school. Sierra certainly doesn’t want another dog, especially one that reminds her of her father. And she definitely doesn’t want to see Mike with that charming smile of his…
 
But Trooper has a mission of his own. Before too long Mike is moving to the ranch to lend a hand—and hoping for his own second chance with Sierra.
