Slayers Give Happy Endings - The Slayer's Reverse Harem, #5

Belle Harrison, vampire slayer, has just leveled up spectacularly. She's thirstier. And sensier. Yes, that's a word now. But her new dead life isn't all bloody cocktails and hot sex with her three gorgeous vampires. The dark unknown who wants Belle dead-permanently-has been up to no good. It's time to take him down. No problem, right? Wrong. No slayer has ever survived until their twenty-first birthday except one, and he lost his damn mind.
And something's not quite right with Belle's.
