The Kheld King by L.L. Stephens

The King is dead. Long live the Kheld King. The Triempery lies crippled, its godborn princes slaughtered by treachery, its ruling houses desperate to maintain their monopoly of the god-machine Entities. In the aftermath of the slaughter, Stefan Stauberg-Randolph inherits his grandfather's throne. Already an outsider because of his Kheld heritage, Stefan sees enemies around every corner--but he particularly fears Dorilian Sordaneon, sole surviving heir of the Rill Entity's power. Set upon conflicting paths by betrayal and suspicion, the animosity between the two young rulers could well threaten not only the Triempery's remaining houses, but the Entities themselves.

Sordaneon (The Triempery Revelations Book 1) by L.L Stephens

Secrets sheathe swords. A fallen world is littered with the corpses of broken god-machines, and a sheltered, angry youth is destined to re-awaken their power. But to embody a god, Dorilian Sordaneon must first learn to be human... Dorilian is blood bound to the Rill, a quasi-living artifact that spans continents and empowers a privileged few to reap the riches of an entire civilization. Unfortunately, decades after seizing control of the remaining god-machines, those privileged few aren’t willing to give up their power—even if it means destroying the human bloodline to which the Rill is tethered.
