I just couldn't put it down although I had to, at great distress (work & child requiring my attention).In one respect, I didn't find it as impressionable as the first book, [b:The Girl with a Dragon Tattoo|10323866|The Girl with the Dragon Tattoo A WikiFocus Book (WikiFocus Book Series)|George Andersen|http://ecx.images-amazon.com/images/I/5176uLNOKsL._SL75_.jpg|15226291], but that's because it's not as 'graphically' violent as the first book. However, I do not particularly enjoy violent books so this is actually an acceptable factor to me.Another aspect of the first book was that it was filled with many economic references / comments which just did not hold my attention and therefore, bored me. However, this second book is completely different: barely makes mention of economic jargons but has many refereces to mathematics (which I am embarrased to confess, I actually enjoyed!).Overall, a truly enjoyable read but did not quite reach the 5 stars rate.
