The Oathbound Devil (en Inglés) - S.J. Brown

Neither meticulous training nor the walls of a carefully-constructed façade could have prepared him for her.

Infernal-blooded Ramiren Orasti's past continues to haunt him. To distract himself, for four decades, he has traveled across nations and even worlds to provide his services as a binder of contracts and pactmaker. And he has done so alone.

He even convinced himself he preferred it that way. It's safer to not get attached.

Yet one fateful trip to a Fey Carnival threw his world into chaos. Nothing has gone according to plan since, and that includes the celestial protector now bound to him.

They are both marked by the arch-devil Vrakus, and Ramiren isn't entirely sure he understands why.

When old enemies show their faces outside of Camlynn's gates, Ramiren and Nathalia must work together to overcome an existential threat that could break Laeth in two.

But what about Vrakus?

It has been a month since their escape from Wistran and the Feylands. Surely, he's forgotten all about their agreement and won't come to collect.

Right?
