It's no The Last Wave
, probably veering more toward The Wicker Man
, but the spooky post-hippie one with Edward Woodward rather than the crazy Nic Cage one with bees.*
It's full of casually fine detail and witty prose, which makes up for it being too long.
It's genuinely creepy and freaky in parts, some gorgeously unpleasant and yet beautiful images, many involving spiders, and generically reminiscent of a few too many previous bad-things-happened-when-I-was-a-kid-but-now-as-an-adult-I'm-back-to-fight-that-evil storylines.
It's a fast read, and better than much contemporary horror fiction.
I got your mascot right here, baby.
