Very well written. First-person account of a psychopath or maybe a sociopath living deep inside a metaphor in Scotland. Very unsettling, with a narrator who's clearly unreliable, so one is always wondering if incidents or even entire characters are imaginary. Although certain twists were heavily foreshadowed, the denoument was still quite tense. My only qualm is that I think the final few pages spelled out too much -- it would have been more haunting if the narrator didnt become suddenly insightful and deconstruct the metaphor.
Havent been so compelled to turn pages in a while.
