Blood Legacy — Michael A. Stackpole

THEY HAVE ARRIVED.
The Clan invaders have chosen their next objective--Luthien, capital of the Draconis Combine. House Kurita must now fight for survival on its homeworld.

NOTHING WE HAVE CAN STOP THEM.
Hanse Davion is presented with a situation undreamt of...final defeat of the Dragon--House Kurita. Should he attack his distracted foe and destroy the enemy his family has battled for over 300 years? Or should he reinforce a fellow House of the Inner Sphere against a force that Davion and the Federated Commonwealth might not otherwise defeat when the time comes?

Since appearing in the Inner Sphere, the Clans have moved from planet to planet with utter disregard for any opposing force. Their technology is superior to anything the Inner Sphere possesses. Their race is selectively bred for combat. They appear to be unstoppable.

HUMANITY'S ONLY HOPE--AN ALLIANCE OF MORTAL ENEMIES--MAY BE DOOMED.
ComStar, the semi-mystic sect that controls interstellar communication, moves to engineer circumstances that will hurl Davion, Kurita, and the Clans into a war that will leave ComStar in a position to dominate what was once the Star League.
