In the Stormy Red Sky by David Drake 2009
A Cinnabar Senator furious at losing an election and still powerful enough to make her anger deadly.
The boy ruler of a star cluster who thinks he's a god and who can sign the death warrants of even Cinnabar officials if a mad whimsy tells him to.
A world of slaves and escaped slaves, where the most savage beasts in the jungle used to be human. An enemy base that could shrug off attack by powerful battlefleets but which must fall to a single cruiser if Cinnabar is to survive.
From palace to reeking jungle, from gunfights in grimy hangars to the flagship's bridge during a sprawling space battle, Leary and Mundy are in the thick of it again.
