I thoroughly enjoyed reading this book, because it always had me returning for more. I wanted to press on through the book due to the captivating storyline and characters; I wanted to see how it all developed and what the grand finale would be. It was just refreshing to find such a well written, engrossing book which you could settle down to every night.
The characters are this book's forte. Lisbeth Salander is portrayed in a peculiar way; she is shown in a sociopath light, who is just strange and is not interested in any kind of conversation unless it is to do with her work, but as the book develops and as Lisbeth develops, you begin to be enlightened to more of Lisbeth's past. Her past makes the character such an interesting fictional character and makes you always question what's next? Mikael Blomkvist is probably the complete polar opposite of Lisbeth and what is so captivating about this book is reading about how his relationship with Lisbeth progresses and evolves as certain things occur around them.
This book does not shy away from the element of love and sex; they're crucial in the development of the characters and to further iterations of the Millenium series. However, it also would quench the thirst of anyone looking for a magnificent crime thriller.
It is successful on many levels. I would certainly recommend that you read this book and continue on in the Millenium trilogy. The characters develop a huge amount in the second book so there is a lot more to still be had after this book.
