I feel like every Gillian Flynn book I read has even more fucked-up characters than the last. Except the first one I tackled was her most recent, [b:Gone Girl|8442457|Gone Girl|Gillian Flynn|http://d202m5krfqbpi5.cloudfront.net/books/1339602131s/8442457.jpg|13306276], and finished up with this one (her debut), so maybe it's actually the opposite. In any case, [b:Sharp Objects|66559|Sharp Objects|Gillian Flynn|http://d202m5krfqbpi5.cloudfront.net/books/1298431315s/66559.jpg|3801] was totally horrifying and I loved every minute of it.
I did suspect the killer fairly early on, but then I kept rethinking my suspicion so that didn't detract from the book or make it any less suspenseful. As with Flynn's other books, I found this one totally riveting.
Trigger warning for cutting, though I actually didn't find it as triggering as I expected from the description. Still, I try to warn about these things in case others are more sensitive.
