Against Me: a Cedar Tree novel (Cedar Tree, 3)

Patience has always been Caleb Whitetail's strength. Quiet and unassuming is what you see with the GFI investigator, but the blood boils hot right under the surface. He kept his distance for years only to see the woman who has held his attention almost lose her life not just once, but twice. He is done standing in the shadows.
Katie Acker, once a tough and athletic security specialist now struggles daily to walk. The closest to family she has are her colleagues at GFI. Especially the man who saved her life and always has her back. So when she unwittingly becomes the focus of a Mexican cartel, it's no big surprise she finds him right by her side.
With the combustive change in their deepening bond, Katie and Caleb do not see the oncoming danger - until it surrounds them.
