If you're searching for your next epic space opera series, Christopher Ruocchio's The Sun Eater is one of the most ambitious and acclaimed science fiction sagas of recent years. Often compared to Frank Herbert's Dune and Patrick Rothfuss's The Name of the Wind, this series blends the grandeur of space opera with the intimacy of epic fantasy, delivering a story that spans millennia and explores the depths of what it means to be human.
Set 20,000 years in the future within the sprawling Sollan Empire, The Sun Eater follows Hadrian Marlowe; a man remembered both as humanity's greatest hero and its most terrible monster. The series is told as Hadrian's memoirs, a confessional narrative in which he recounts the events that led to him becoming the Sun Eater: the man who destroyed a star and killed billions, including the Emperor himself.
Whether you're a fan of character-driven science fiction, intricate worldbuilding, or philosophical explorations wrapped in thrilling action, The Sun Eater delivers on all fronts. This complete reading guide will help you navigate the series in the optimal order.

Queen Amid Ashes
by Christopher Ruocchio
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.--

To make matters worse, a cult of personality has formed around Hadrian, spurred on by legends of his having defied death itself. Men call him Halfmortal. Hadrian’s rise to prominence proves dangerous to himself and his team, as pressures within the Imperial government distrust or resent his new influence.

The Dregs of Empire
by Christopher Ruocchio
Return to the world of the Sun Eater in this spin-off adventure set after the events of book five! For thousands of years, the icy planet of Belusha has served the galactic Sollan Empire as its most notorious prison planet. It is here the very worst men in the Empire are locked away: murderers, traitors, deserters--each condemned to toil on the oil rigs and scrapyards of the planet in bitter cold, preyed upon both by the men of the Martian Guard set to watch over them, and by the Outborn reavers whose fathers escaped the work camps to scratch a living from the icy wilderness. It is a hard world. A desperate world. And it is here that Lorian Aristedes finds himself: alone; friendless; betrayed even by his own failing, mutant flesh. It is here that Lorian Aristedes has been sentenced to work himself to death for the crime of abetting his master's escape from imperial justice. For any other man, it would be the end of his story ... but for Lorian Aristedes--once the left hand of the Halfmortal, Hadrian Marlowe himself--it is only the beginning.
