Beasts by Serena Knights

When my sorority turned on me, I knew something was off.
Desperation led me to an unexpected refuge—a fraternity house shrouded in secrets. Thirteen demons call this place home, and to my shock, their powers can’t touch me. My greatest fear has always been vampires, thanks to a haunting childhood memory. But when I meet the vampire in the attic, everything changes.
He’s different, and despite my terror, I’m drawn into the college play with him as my co-star. As our rehearsals bring us closer, a sweet, forbidden romance begins to bloom. Amidst this, I start to build a new family with these demons, discovering there’s more to me than I ever imagined. But darkness looms over this newfound family.

The head vampire discovers my presence, and a chilling ultimatum is laid before them: someone must pay for spilling their secret to a human.
Sacrifice themselves, or sacrifice me.
