In 1990 Michael A. Stackpole's novel Lethal Heritage introduced readers to the Clans, genetically enhanced MechWarriors from beyond the Periphery who returned to the Inner Sphere to conquer the Successor States. With advanced BattleMechs and unstoppable skills, they crushed all who stood in their way—changing the BattleTech universe forever. Now, in Onslaught: Tales of the Clan Invasion!, seven stories have been gathered from the BattleCorps fiction website to showcase this universe-altering event. Seven stories of incredible attacks from beyond known space. Seven stories of unremitting heroism in the face of defeat. Seven stories of the onslaught of the Clans.
