Queen Amid Ashes(Sun Eater‪)‬

THOUGH THE BATTLE TO SAVE A PLANET IS OVER, THE WAR NEVER ENDS.
Hadrian Marlowe is newly a knight of the galaxy-spanning Sollan Empire: a hero who they say slew the alien Prince Aranata Otiolo in single combat; a man they say no man or xenobite can kill.
Acting on the Emperor’s orders, Hadrian has come to the desert planet Thagura and driven off the Cielcin invaders, rescuing in the process the Lady Gadar Malyan, Baroness of that entire world.
But not all the fighting is ended. Pockets of inhuman resistance remain on the desert world, and Hadrian the Halfmortal must soon do battle with not only the man-eating alien barbarians, but with something just as terrible: man’s own inhumanity to man.
