In this continuation of the story Cramer began in The Daughters of Caleb Bender/Paradise Valley, troubles intensify in The Captive Heart as Caleb Bender's family tries to settle into their new life in 1920s Mexico. When El Pantera kidnaps Rachel and leaves her brother, Aaron, for dead, Jake Weaver and the Mexican native Domingo pursue the bandit leader to his mountain stronghold in a hopeless rescue attempt. Jake and Domingo manage to escape with Rachel, with the bandits hot on their trail. In a desperate attempt to avoid recapture, Domingo puts himself squarely in harm's way, giving Jake and Rachel time to get away. This is not the quiet life Caleb Bender envisioned when he led his family out of Ohio. What is a father to make of his daughter's obvious affection for a man outside the fold? And how will a pacifist Amishman like Caleb respond to the events that threaten his family and their way of life?
