Book excerpt: Out of nowhere, Walker Cody swoops in and saves Paula Olsen's toddler son from a dog bite. Before she can properly thank him, the handsome Iraq War veteran fades into the crowd. Walker's in training to retake his World Champion Bulldogger title. The practice rides are bruising, but still don't knock thoughts of a certain beautiful young widow and her little boy out of his head. And Paula's shocked to realize she has a bad case of Pervasive Walkeritis. Survivors' guilt and ghosts from their pasts stand between them. Walker's need to prove himself on the rodeo circuit runs deeper than bragging rights. But can Paula risk her healing heart on a troubled man who deliberately puts himself in danger?
