I continue to enjoy the Sun Eater series because Ruocchio combines elegant prose, literary and historical allusions, expansive world-building, and long-form revelations with an engrossing story. I am increasingly disappointed, however, by the series’ movement away from science fiction toward high fantasy: Watchers, Titans, lesser gods, and greater gods now occupy an expanding role, while the underlying metaphysics increasingly resembles an arbitrary magic system. Ruocchio is no longer using fun frontier cosmology and physics, such as ten-dimensional reality with multiple time dimensions. He has replaced them with fantasy conventions. This shift away from science and my love of Golden Age science fiction are eroding the fun as the series progresses.
Nearly two centuries after Ashes of Man, Hadrian lives in exile on Jadd with his daughter Cassandra when the Emperor recalls him to service. HAPSIS, the emperor's secret ancient god "Watcher" investigation department, has located a Watcher, a being worshipped as a god by the evil Cielcin, and Hadrian receives an almost impossible assignment: kill the watcher.
I am still invested in Hadrian’s story. I enjoy watching his character evolve as centuries of experience, accumulated power, guilt, and loss reshape him, while Cassandra introduces a new dimension to a protagonist who has spent most of the series isolated by circumstance. The revelations continue to reframe earlier events, and the stakes now extend beyond interstellar war into the nature of reality itself. Hadrian increasingly resembles a fantasy hero leveling up, acquiring powers sufficient to confront progressively more consequential enemies and quests. I would prefer more scientific constraint and less arbitrary metaphysics, but Ruocchio’s prose, character arcs, historical texture, foreshadowing, and world-building keep me engrossed. I continue to enjoy the Sun Eater series, even as its increasingly fantastic direction moves it further from the science fiction I love most.
