In Ruby the Foster Dog by Jimmy Wayne, Ruby, an adorable mixed breed puppy with an underbite, wonders if a family will ever adopt her. When a goofy looking, scruffy-faced man stops by the shelter, he adopts Ruby. Mr. James is not the family she was expecting, but could he still be the answer to her prayers? Mr. James (known as Jimmy Wayne to his country music fans) is walking halfway across America to raise awareness for the thousands of foster children who desperately need our help. Ruby realizes that she's not so very different from these kids: she is scared and alone. If she doesn't have help, she can't have hope either. But Mr. James wants to change all that, for her and for every foster kid in the United States.

On their adventure together, Mr. James teaches her about integrity, honesty, loyalty, faith, forgiveness, and trust, but mostly how love can rescue someone and forever change lives. As they walk along historic routes and locations throughout the Southeastern United States, Ruby quietly helps Mr. James over- come the issues he's been struggling with too. By the time they get to Phoenix, both of their lives are changed for the better. But just when Ruby accepts Mr. James as her new family, an unexpected phone call challenges her to redefine family and love all over again.
