Day 8 - A book that scares you
Candlenight by Phil Rickman. I've read almost all of his books and really enjoy them (even more so now that I've visited some of the locations mentioned). Candlenight was the first of his books that I read, and it and the novels that followed utterly terrified me. Supernatural horror.
Special mentions also go to The Name of the Rose by Umberto Eco and The Haunting by Margaret Mahy, which scared the crap out of me as an 11 year old.
