The atmosphere of Lost Souls is probably some of Jackson's best work (that I've read thus far). Maybe it's because I read the book while attending college during a particularly wet and misty autumn semester, but he descriptions of the All Saints campus made me shiver, and I still catch myself remembering how tense I felt while curling up with this one. The story is pretty good, though I was rather put off by the ending - Jackson has a tendency to throw out a random person for the big killer reveal at the end of her books, which serves its purpose in ensuring the reader won't be able to properly figure the mystery out, but also annoys some of us to no end because of how completely impossible it would have been to finger the perp. Still, overall one of her better efforts and well worth the read.
