In the darkest years of the Great Depression, two unlikely companions wander the American West aboard freight trains and through forgotten towns. Their lives change forever when they stumble upon a mysterious map connected to an ancient Aztec legacy.

As rivals close in and long-buried secrets emerge, the trail leads far beyond the hardships of the 1930s-into a saga of conquistadors, frontiersmen, and generations bound by blood and legend.

Boxcars and Bloodlines is a sweeping historical adventure about friendship, legacy, myth, and the enduring power of the past.
