The Knights: When the Siren Calls (Book One)
Kai isn't your typical college student. He doesn't party, drink, socialise or even date. Probably because he's busy hunting demons before they start killing other humans.
Kai knows he isn't human, but if nothing else, being an Incubus is quite useful for blending in and for bouncing back after a manticore tries to eat you. The only downside, what happens when the enemy is the gorgeous young bartender who has him under her spell?
