Would have been four stars if I'd ever warmed up to the heroine. There was something empty about her, very hard to latch onto. Which is a shame, because I enjoyed pretty much all the supporting characters, especially the scenery-chewy Southern Gothicky ones, as well as the mythology itself. I'm not sure if it was the fault of the first-person narration, but the main character felt like a vehicle for all the interesting stuff, rather than being interesting herself.
Good Southern Gothic horror, and I will likely pick up the next one eventually.
Extra super bonus points for setting it in Chattanooga, with an extra megatroid bonus for Signal Mountain. My childhood! Right there! With creepy stuff happening! Yay!
