This, R.I.P reading challenge looks rather interesting. I won't be joining it (not with only a month and a huge desire to finish "THoM"), but if I was, I think my books would be:
1. Fahrenheit 451
3. Bleak House
5. Ghost Stories (by Edith Wharton)
Guidelines: pick out any 5 books that you want to read that you think meet the very open, broad criteria of being scary, eerie, moody, dripping with atmosphere, gothic, unsettling, etc.
