Saga of the Gray Death Legion #1 - Decision at Thunder Rift (1st Printing)

Thirty years before the Clan invasion, the crumbling empires of the Inner Sphere were locked in the horror of the Third Succession War. The great Houses, whose territories spanned the stars, used BattleMechs to smash each other into rubble.
Grayson Death Carlyle had been training to be a MechWarrior since he was ten years old, but his graduation came sooner than expected. With his friends and family dead and his father's regiment destroyed, young Grayson finds himself stranded on a world turned hostile. And now he must learn the hardest lesson of all: it takes more than a BattleMech to make a MechWarrior.

To claim the title of MechWarrior all he has to do is capture one of those giant killing machines by himself.

If it doesn't kill him first.
