A legendary band of Texas heroes rides to war one last time. They built a new republic with their blood and courage. But with the battle for Texas independence fought and won, and the Union being torn apart by civil war, a new threat has arisen on the bloody border between Mexico and the Republic of Texas. John Henry McAllen, who formed the Black Jacks to fight alongside Sam Houston to defeat Santa Anna a quarter of a century earlier, hoped his fighting days are over. But when the corrupt sheriff of Brownsville is gunned down by a Mexican ex-soldier, Houston-now the Texas governor-declares martial law. A volunteer force called the Brownsville Tigers is mustered to battle fierce raiders led by the Mexican patriot named Caldero. Yet another war is about to erupt over the disputed southern border of Texas and McAllen's son Gideon, a Brownsville Tiger recruit, is in the middle of it. When Gideon is taken captive, McAllen, followed by his legendary Black Jack fighters, crosses the Rio Grande into a storm of blood and fire, determined to save his boy-or die trying. THE ACCLAIMED AUTHOR OF THE BLACK JACKS AND TEXAS BOUND GIVES US AN AUTHENTIC, ACTION-PACKED NOVEL OF WAR, HONOR AND BETRAYAL BASED ON ACTUAL EVENTS.
