Two boys. One battle. A life-changing encounter.

Jemmy Martin left his Texas farm and followed Confederate General Sibley's Army into New Mexico to keep his mules safe. Now after the Battle of Valverde he's protecting Willie, an orphaned drummer boy with a broken arm. Cian Lochlann is an Irish orphan who gave up gold prospecting to join the Union Army. All he wants is a full belly and a strong man to lead him into an unknown future. Both are pulled toward a distant mountain pass in New Mexico territory where the decisive battle of Gen. Sibley's New Mexico campaign will be fought. Called the "Gettysburg of the West" the Battle of Glorieta Pass will test both boys as they face their worst enemy.
