Sangian: Returning Alan Dean

Conspiracy of Blood.

Holly smiled at the wrong person and soon found herself on a bloodstained road to madness. A paranormal urban fantasy.
Like thousands of others in the city, Holly is trying to make her way outside the mainstream. She's an artist striving to survive, and then she meets someone who changes everything. Beth slides seamlessly into her world and inducts her into ancient rituals that challenge the core of Holly's beliefs and ultimately drive her towards insanity. Only her sister and a worn out police officer teetering on the brink of a breakdown can help, but even they struggle to prevent an outcome that has been ordained for millennia.
