Bloodborn Prince by Laura Lascarso

As a bloodborn Nephilim, Vincent’s power of seduction can compel beings to spill their secrets, but he seeks to know the mysteries of only one man’s soul—those of his protector, Henri.
With the grief of his lover’s fate still fresh, Henri resists Vincent’s amorous advances. Even as the bond between them intensifies, and his self-control falters, Henri won’t risk losing his beloved again.
When Henri takes Vincent as his demon-hunting apprentice, their combined abilities uncover corruption amongst the gods. Tempers flare and loyalties are tested as the lies meant to protect become the same ones that ensnare.
And with divine forces attempting to coerce him at every turn, Henri must distinguish ally from enemy, and truth from deceit if he hopes to protect his bloodborn prince.
