Caleb Tucker is a Texas Ranger. He takes his job seriously and he has been taking care of Belle Doe -- a woman who can't remember who she is or where she comes from. The only thing they both are aware of is someone tried to kill her and she was strong enough to survive. Caleb knows that, eventually, Belle's memory is going to return and she will go back to her old life and leave him behind. It's the way things should be ... now if only he can convince his heart of this. Josie Belle finally remembers her past ... she has a fiance and a life that she needs to return to, but she can't walk away from the one man who makes her feel safe. What do you do when life changes and the rules change? Son of Texas (4), by Linda Warren, is a wonderful romantic read. Caleb and Josie Belle will burrow their way into the hearts of readers. Secondary characters are a charming addition to this emotional read.
