I was looking for mystery/thrillers to read and Gone Girl by Gillian Flynn had been on my Kindle for some time. I bought it on sale, but because I'd seen, and liked, the movie years ago, I didn't bother to read it. I bothered this month, and it is a very good read. I rewatched the movie this past weekend. The ending of the book is much grimmer than the ending of the movie. Interesting point: Writers often read that they must have likable characters, certainly a likable main character. One of Gone Girl's main characters is unlikable and the other is a psychopath. Yet Flynn pulls it off.
So then I decided to read one of Gillian Flynn's earlier books, Dark Places. Holy Moses, it makes Gone Girl look light and fluffy. Interesting point: Talk about unlikable characters! This one has some unlikable child victims. Again, Flynn pulls it off.
Another interesting point: All three of these books use multiple points of view, something I didn't realize was used that much in adult work. With Flynn's books, in particular, you really get different voices with the different point of view characters, something I think doesn't happen a lot with YA and middle grade, in which the characters often sound alike.
