BattleTech Legends: Mercenary's Star (The Gray Death Legion Trilogy, Book Two) - BattleTech Legends, #2

BACKS AGAINST THE WALL... Galatea: the Mercenary's Star. Even the most down on their luck units can find work here. Leading the newly-formed Gray Death Legion is proving to be a hard task for Grayson Death Carlyle, so when a job comes their way, he is only too happy to take it. The job: train the local resistance on the planet Verthandi to resist their Draconis Combine masters. But things do not go well almost from the moment the Legion arrives at Verthandi.
Trapped on the planet and facing a numerically superior force and a fractured populace, the men and women of the Legion find themselves in a situation that makes the campaign on Trellwan look like a walk in the park. And Grayson may find that repeating his successes of the past may not be so easy this time.
