In 1875, sixteen-year-old Card Jordan returns from his first solo hunting trip to discover a nightmare -- his family brutally murdered by a ruthless gang. Scrawled in the dirt beside his mother's body are the words that will forever change his life -- CARD, KILL THEM ALL. Fueled by vengeance and armed with his father's Cavalry hat, Card plunges headlong into a relentless western adventure. He must leave his innocence behind and become a force for frontier justice, tracking the killers through the wilds of North Texas and Indian Territory. Along the way, Card endures heartbreak, illness, and the unforgiving challenges of the Old West, sharpening his skills as a gunfighter with every step. As Card closes in on the gang's vicious leader, Ned Black, his quest for retribution becomes a test of courage, resolve, and the true meaning of justice. Will avenging his family bring him peace -- or only more pain?
