Book Review: The Girl Who Played With Fire Book 2 Millennium Trilogy, by Stieg Larsson and translated by Reg Keeland

I recommend reading book one before this one, you would be lost without it.
Mikael Blomkvist who is a co-owner and journalist for the Millennium magazine, has decided along with Erika Berger (the other owner,) and their staff,  to publish a story about the sex trafficking operation.
They feel it is a story that must be published, yet it might have repercussions.
Lisbeth Salander and Mikael had a relationship both business and sexual in book 1. When this book begins Lisbeth has made herself disappear for a while. Mikael has tried to find her, eventually giving up.  
Lisbeth's past is like a coiling snake, ready to strike.
The Swedish police believe Lisbeth has committed a triple murder. Mikael wants to prove them wrong. During the course of his investigation in order to find her innocent, he uncovers her dark past.

Once again the first 1/2 of book is s-l-o-w, it drags on and on and on--adnauseam.  
I was bored. I wanted the story to hurry up and get there, sorta like a child in the back seat while on a family vacation that keeps asking, "when are we going to get there?"
Mikael seems to not be able to say no to any woman of any age that wants to play peek-a boo. 
Lisbeth begins this story with having a sexual union with an underage boy, later she is back with her on and again off again gal-pal/?whatever.
Finally about mid-point in the book the story picked-up. The last quarter of the book things finally fall together and an a-ha was in store!
Did I like this book? Hmmmmm, it is a good crime novel. I state that as a newby to this genre, so excuse me. I'm not much as you can tell too keen for flagrant lewd stuff. It adds nothing for my reading pleasure.
I would give this book a 5 on a score from 1 to 10. So that's an okay, sorta. 
But, since I have 1 more book to read, and I do want to know what happens to these 2 characters, as well know how the books trilogy ends, I'll read the 3rd and last book.
