The best book I've read recently is Steig Larson's The Girl with the Dragon Tatoo. Give it a chance - it's a great book.
Once the action starts, this book is a roller coaster ride. There are several intense relationships that are explored and resolved. This book not only kept my interest, I had trouble putting it down in order to get anything else done :)
Mikael Blomvquist is a flawed man and that makes the character interesting. He has his own moral belief system, which seems quite different from the "typical" (is there such a thing?) American Judeo-Christian morality. I think it's because he is European, as is the author. Whatever the reason, I find him fascinating. I want to read more about him - in fact, I have already purchased books 2 & 3.
