BattleTech Legends: Decision at Thunder Rift: (The Gray Death Legion Trilogy, Book One)

Thirty meters tall, 70 tons of quick-striding death and destruction, the armored war machines called BattleMechs are the fighting force of the crumbling star empire locked in the horror of the Succession Wars. Their pilots are MechWarriors, 31st-century knights riding armored machines powerful enough to destroy an entire city.

Grayson Death Carlyle had been training to be a MechWarrior since he was 10 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, all he has to do is capture one of those giant killing machines by himself... If it doesn't kill him first.
