I was determined to finish the book. With terrorism and hatred of immigrants enmeshed in the storyline, it should have been a book challenging to put down, but it was not. I have thought several days about why I found it a difficult book to finish. There are several reasons. The storyline felt disjointed. I understand that in a series, the author does not want to spend much time on backstory. The successful author can incorporate enough information into the writing to make readers feel empathy toward the main characters, but I could not connect with anyone. As an American reader, I got confused by the Swedish names, to my ear and eye they were so similar that I kept getting mixed up. Geography also seemed to be important in the storyline, and perhaps having a map of Sweden would have helped me make sense of what was going on.
