National bestselling author E. E. Knight revisits the Vampire Earth to tell a tale about David Valentine’s fellow freedom fighter Ahn-Kha.... Captured and sold to the Kurian-allied Maynes Conglomerate to work as a slave in the coal mines of Appalachia, Ahn-Kha is angered and appalled by the dangerous working conditions and the brutal treatment inflicted upon his fellow miners. When a protest against shortages is deliberately and bloodily suppressed, Ahn-Kha sets himself against the ruling Maynes family and sets out on a trail of vengeance through the Coal Country. The people of the Coal Country now have a leader—a powerful and battle-hardened leader determined to forge them into an army that will wage guerrilla warfare against the Maynes family and their Kurian masters—and free the Appalachians from their tyranny.... Adapted from the novel and produced with a full cast of actors, immersive sound effects and cinematic music!
