Tytania (2008)

Blurb:
Through fear and conquest, the Empire of Valdana holds the future of most of human space within its iron hands … and for generations, those hands have belonged to the Landless Lords of the ruling Tytania dynasty. But now that the foundation of the empire is crumbling, pockets of rebellion are forming. When a mission sent to punish the city-state of Euriya is shockingly defeated, the man responsible becomes the target of a galaxy-wide manhunt!

For Fan Hyurlick, architect of Tytania’s first defeat, glory becomes desperation as his own side betrays him. Now Fan must not only save his own life, but somehow turn the tables on opponents who have whole worlds to command!
