Mechwarrior: Dark Age #2: A Call to Arms (A BattleTech Novel): A Call to Arms (A Battletech Novel)

Months have passed since the interplanetary communications net was destroyed, isolating planets across the Republic of the Sphere. Achernar is one of the few worlds still in possession of a working Hyperpulse Generator Station, capable of communications across the galaxy—and a much sought-after prize for the splintering factions of the Republic to acquire.

But when the Swordsworn desert Achernar in its time of need, Raul discovers that there’s little honor in the brutal realities of war and the subtle nuances of treachery...
