The Rebellion. The Stonetellers, Volume One

Jean Rabe returns to the world of Dragonlance with a tale of slavery, rebellion, and the struggle for freedom! When a series of earthquakes strike a Dark Knight mining camp, goblin and hobgoblin slaves take advantage of the bedlam and revolt. A fast and deadly rebellion erupts, pitting the Dark Knights against their slaves... and against the still-rumbling ground. Casualties on both sides climb as a leader emerges among the slave force --Direfang, a hobgoblin foreman with deep scars and a long, brutal history of servitude.
He must rally the surviving goblins and hobgoblins and lead them out of Neraka, turning his rag-tag force into an army that will not allow itself to be enslaved again.
