Dragon Rising: A Battletech Novel (Mechwarrior: Dark Age, #24)

Jade Falcon Galaxy Commander Malvina Hazen and her warriors on the planet Skye receive a visit from a Hell's Horses ship, whose commander issues a Trial of Possession for the wartime doctrine he claims Malvina stole from his Clan. Although she bests her opponent in single BattleTech combat, Malvina's actions may herald the beginnings of a civil war that could unmake the Clan-and the galaxy.
