The Captive Trail is part of a six-book series about four generations of the Morgan family living, fighting, and thriving amidst a turbulent Texas history spanning from 1845 to 1896. Although a series, each book can be read on its own.
 Taabe Waipu has run away from her Comanche village and is fleeing south in Texas on a horse she stole from a dowry left outside her family's teepee. The horse has an accident and she is left on foot, injured and exhausted. She staggers onto a road near Fort Chadbourne and collapses.
On one of the first runs through Texas, Butterfield Overland Mail Company driver Ned Bright carries two Ursuline nuns returning to their mission station. They come across Taabe who is nearly dead from exposure and dehydration and take her to the mission.
With some detective work, Ned discovers Taabe Waipu's identity. He plans to unite her with her family, but the Comanche have other ideas. Through Taabe and Ned we learn the true meaning of healing and restoration amid seemingly powerless situations.
