Grace O'Malley's people are valiantly making a stand against Loren Hanson's Roughriders, a band of mercenaries destroying everything in their path. Badly outnumbered, her forces need real BattleMechs operated by trained MechWarriors. And they're not going to be easy to afford, especially since the the big mine owners refuse to offer any funds for planetary defense. But Grace will not surrender her homeland, no matter what the price.

Even though the ragtag locals are putting up a suprisingly good fight, Hanson remains confident he can defeat them. What he doesn't count on is an opponent determined to write her planet's history in the scorched wreckage of the battlefield
