Everyone compares this book to the Stieg Larson trilogy, and while there are some similarities, I don't think they have too much in common. (Other than a lot of words that you'll never be able to pronounce.) The Dragon Tattoo series is a very involved trilogy, with a lot of different plot stories, an overall plot that lasts for three books, and some very involved characters. The Nesbo book (this is the first I've read) is a bit different. It can definitely be read on its own, and doesn't need to be followed up with a sequel. The story could continue, but you also get a pretty good ending to the story.

The plot itself is pretty well written and keeps the book moving at a fast pace. There are quite a few twists and turns in the novel, and you are kept guessing until the very end. The characters are interesting, although you don't really connect with them like you do the Larson characters. But all in all, it's a good story and will keep you entertained while you read it. (Not a spoiler, but just keep an eye out for the mold guy, and if someone figures out what the hell he means, let me know!)
