Dr. Joe Granger is used to emergencies, but nothing prepares him for the one waiting on his doorstep. Marissa Johnson, his late ex-wife's sister, has just arrived in Crossroads Creek with Delia, a seven-year-old girl she claims is his daughter. Marissa seems sincere enough, but knowing the facts of the past, Joe finds himself torn between disbelief and a long-buried dream of having a family.

As Delia's legal guardian and aunt, Marissa felt compelled to bring Delia to meet Joe. Having been more of a mother to the young girl, she doesn't know how things will turn out, but she knows introducing them is the right thing to do. Reluctantly, she agrees to stay for two weeks, giving Joe time to get to know Delia as they wait for the paternity test results. But balancing his long work hours, emergency ranch calls, and bonding time with Delia pushes Joe to his limits-and leaves Marissa more than a little frustrated.

Meanwhile, Marissa, a writer with a stubborn case of writer's block, finds her creative spark reignited in Crossroads Creek. Her new story, which is beginning to mirror her growing connection with Joe is unsettling. Marissa knows she can't let her heart get involved, especially not with her sister's ex-husband, and especially since she plans on taking Delia back to Dallas.

As the paternity test results loom, Joe realizes that custody decisions could tear apart the fragile bond they've built. Now, Joe must decide if he's willing to fight for the family he never expected but can't imagine losing. Rediscover the magic of new beginnings and the healing power of God's love in this heartwarming journey through family, faith, and second chances in The Dream of a Cowboy.
