Forged in Fire by Juliette Cross

She didn’t know the demon world existed. Now she just wants to survive it.

Genevieve Drake has never been the helpless kind of girl. Never needed a man to come to her rescue. That is, not until her twentieth birthday when some dude nearly chokes her to death in an alley and a hot stranger splits the guy in half, rips a monster from inside, and incinerates it into ash.
The hot guy? Jude Delacroix—Master of Demons. Now her guardian, whether she likes it or not. But she’s seriously beginning to like it.
The dude choking her? One of many demons from the underworld trying to abduct or kill her. As the prime target of the demon prince, Danté, who has all kinds of lascivious and sadistic plans, she has no problem accepting Jude’s protection.
Why Genevieve? She’s a Vessel, one who is born to serve the Light but can be corrupted and used as a weapon for darkness. Until that fateful night, she had no idea this world even existed. Now, she just wants to survive it.
