BattleTech Legends: Bred for War - BattleTech Legends, #38

TO KEEP THE PEACE... Along with the throne of the Federated Commonwealth, Prince Victor Steiner-Davion inherited a number of problems. Foremost among them is the Clans' threat to the peace of the Inner Sphere-and a treacherous sister who wants to supplant him. The expected demise of Joshua Marik-heir to the Free Worlds League, whose very presence maintained peace-also endangers harmony. Victor's idea is to use a double for Joshua, a necessary deception to prevent all-out war.
But secret duplicity is hard to maintain, and conflict erupts anyway, splitting the Inner Sphere and leaving the Federated Commonwealth defenseless. And when Victor thinks things can get no worse, word comes that the Clans, once again, have brought war to the Inner Sphere...
