Help, My Stalker Is A Vampire by Storm Song

Celeste seeks solace in her darkest desires. After a heart-wrenching breakup, she pours her longing for thrill and submission into an anonymous blog, confessing her secret yearning to be stalked and used. Little does she know, her words beckon a force far beyond her imagination.
Enter Nash Rigby, a brooding and enigmatic figure, wealthy and powerful, yet harboring a secret that defies the boundaries of mortal comprehension. As a vigilante for the LGBT community, Nash prowls the night as both protector and predator. Drawn to Celeste’s vulnerability, he proposes a dangerous game—a consensual hunt fueled by desire and longing, guided only by a single photograph.
But as their twisted dance ensues, the city becomes a battleground for a darker evil, and Nash finds himself torn between his duty to protect and his growing obsession with Celeste. With killings on the rise and shadows closing in, Nash must unravel the sinister web entangling them before Celeste becomes the next victim of a darkness that threatens to consume them both.
