BattleTech: Blood of Kerensky Books in Order

The Clans invade from beyond the Periphery with military strength the Inner Sphere cannot match. Longtime enemies in the Federated Commonwealth and Draconis Combine must consider cooperation if they hope to withstand the approaching threat.

The Clans' invasion devastates the Inner Sphere, forcing the Five Successor Houses toward an uneasy alliance. Cooperation becomes essential to resisting the attackers, but longstanding rivalries make holding that coalition together another challenge in the continuing war.

The Clan invasion advances with secret support from ComStar, whose leaders have plans beyond assisting the attackers. Efforts to defend the Inner Sphere become entangled with an organization seeking to unite its worlds under a single authority.
