The capital runs on vows.
On Oath Day, it devours them.
Kael Marrin was never meant to survive it.
Marked as PENDING, hunted by the Crown, and tethered to forces he barely understands, Kael enters the capital to uncover the truth behind the Engine-a system built to harvest the power of human promises.
What he finds is worse.
This isn't a kingdom ruled by magic.
It's a system built to consume it.
A city turned into a circuit.
A crowd turned into fuel.
And a ritual so precise it turns obedience into something people call choice.
To stop it, Kael must pull off an impossible heist beneath the heart of the capital-stealing a relic that can cut vows themselves. But every answer leads deeper into the machine, and every move tightens the net around him and those closest to him.
Because the Engine doesn't want Kael dead.
It wants him complete.
And it's already started.
For readers who enjoy:
- Dark, high-stakes fantasy with real consequences
- Heists, relic magic, and system-driven worlds
- Found family under pressure
- Stories where power always has a cost
The Devouring Oath is Book 5 in the Oathbound Relics series-where every promise can be weaponized, and every system has a price.
