It's been a while since I read this book so I can only really be general in review of it. There was only one character that I liked in the whole book. Everyone else was either boring or depressing.
The question of whodunnit kept me reading to the end, but the content wasn't exciting enough to make me want to read the others in the series.
However, I do think that my disinterest in this particular book is completely personal and if you are into this genre you should check out because the actual quality of writing isn't bad.
