Conventions of War (Dread Empire's Fall, Bk. 3)

Working on the opposite sides of the galaxy - one in deep space, the other undercover on an occupied planet - and haunted by personal ghosts, Captain Gareth Martinez and Lieutenant Lady Caroline Sula fight to save the Empire from the vicious, alien Naxid. In a desperate bid to stop the Naxid fleet, Martinez makes a move that could win the war . . . and lose his career. Meanwhile, Sula's guerilla tactics may not be enough to stop the Naxid, so she's forced to try one final, deadly gambit.
