Shadows Upon Time (Sun Eater #7)

The seventh and final novel in the Sun Eater series, Shadows Upon Time by Christopher Ruocchio, concludes the galaxy-spanning saga with a blend of space opera and epic fantasy. Hadrian Marlowe, a fugitive after his victory at Vorgossos, is on the run from both the Extrasolarians and the betrayed Sollan Empire. Hidden beyond human space, he awaits his last ally, the Jaddian Prince Kaim-Olorin du Otranto.

While the inhuman Cielcin have been absent for over a century, Hadrian knows they are gathering strength for a final assault on humanity. He is the only one who can stop them, wielding the ancient war machine known as the Demiurge, forged by daimon machines. Hadrian must confront the Cielcin horde, their Prophet-King, and the dark gods who shaped the universe.
