The Girl In The Spider's Web, by David Lagerkrantz (MacLehose Press, 2015)
I, like many others, loved the first three books in Steig Larsson's Millennium Series, and I, like many others, was very sceptical about its continuation by a different author. When it started to get very good reviews, however, I decided to give it a go, and I'm very pleased I did. Although the prose is ever so slightly clunky in places, especially early in the book, this may be due to the use of a different translator to the earlier books. The characterisation and plotting are superb, at least as strong as in the originals. The typically complex plot is very zeitgeist, involving both the NSA, and Russian gangsters, as well as lots of computer hacking, artificial intelligence, autistic savants, and a high body count. The storytelling involves a lot of action in different places all unfolding simultaneously, and quite a few changes in character's point of view, but the reader is never lost.
I wonder if there will be another one?
