Mechwarior: Dark Age #10

A Clan Jade Falcon force is en route to eradicate the Steel Wolves—but its true mission is the subjugation of The Republic of the Sphere. Constrained by an imposed peace for decades, the Falcons now embark on their most spectacular war in generations—and their lust for blood runs hot...
 
Siblings Malvina and Aleks are Jade Falcon’s best and brightest MechWarriors. Each achieved high command at a young age, and their bond is strong, but so is their rivalry. While Aleks believes warriors should protect the weak, Malvina is obsessed with dark visions of power and glory. If the leader of the Clan is destined to rule the Inner Sphere, then Malvina’s first step toward seizing that role for herself is to conquer The Republic...or utterly destroy it.
