This didn't work for me, and I ended up skimming about two-thirds of it to the ending. While Farris's writing is straightforward and effective, and the story was considerably more focussed and better paced than the last Farris I read (The Fury, which wanders about all over the place, chasing every 70s hot-button it sees in the distance), it still didn't draw me in.
I did like the main character, Chase, and empathised with her, both with her tough, resilient teenage self, and with her wary, fragile adult self. Crow Tilman, the villain was more nebulous. It felt as if Farris was going for a sort of Randall Flagg aura, the chuckling psychopath who is More Than He Seems, and while Crow was plenty scary as an earthbound crazy, once he gained his beyond-the-grave superpowers, he somehow became less scary, less personified, and more like an impersonal run of really crappy luck. So even though Crow could strike from anywhere!!, he felt like less of a threat. YMMV, of course.
Then there was Adam, our hero. And he was what caused me to bail. Seriously, dude, you are a stalker. You don't know anything about Chase except that you want to get close to her. You abuse your cop privileges to learn about Chase, to follow her, and to manoeuvre her into looking to you for help. You are creepy. I read the first third of the book expecting to learn that you were either Crow reincarnated or possessed. But no, this is our knight in shining armour, folks. This is the choice that the plot offers Chase: fall prey to the crazy murderous undead stalker, or seek refuge with the creepy manipulative living stalker.
Well, it is horror.
