When dog trainer Kaitlin Mathers is attacked, Texas K–9 Unit captain Slade McNeal is determined to keep her–and what's left of his family–safe from harm. But Slade soon knows nothing's safe, including his dogs, his son or the beautiful woman who's opening his heart.

When Slade realises the enemy might be closer than he ever dreamed possible, he vows to see justice served. But can he save Kaitlin before it's too late to tell her he loves her?
