The Girl in the Spider's Web

I liked the book and I believe the writing was true to the original author and to the characters. My only problem is it doesnt feel finished, granted in order to continue the series there must be some questions left over but the thing the original series did very well was leave each book feeling complete on it's own. I didn't get that sense from this one.
Perhaps I need to read this one again. Overall it was an enjoyable book with some further fantastic insight into the characters. However, it really is a shame that steig passed before he was able to complete his masterpiece.
