BattleTech Legends: Black Dragon - BattleTech Legends, #12

IN THE CLAWS OF A REBELLION... Theodore Kurita, samurai tyrant of the mighty Draconis Combine, is celebrating his sixty-first birthday. Topping the guest list is an unlikely bunch of high-tech troublemakers: Camacho's Caballeros, the toughest team of mercenary MechWarriors the Inner Sphere has ever seen. But their invitation is more than merely social. Theodore's powerful cousin has recruited their ace operative, Cassie Suthorn, for a dangerous mission.
On a xenophobic planet where honor and duty are worshiped like deities, the freelancing Caballeros are considered barbarians. But Cassie's covert investigation uncovers an insurrection, and Camacho's foreign "barbarians" could be the only unit with enough guns and grit to save the Draconis Combine from its own extremists. And when the armor-piercing rockets and laser fire finally subside, counted among the slain may be Cassie and her courageous comrades-as well as the fragile peace of the entire Inner Sphere...
