This was the first book by the writing duo Roslund and Hellström that I read, but it was certainly not my last. While it's been a while since I read the book, I see I rewarded it five stars.
I remember it as thought-provoking. It's not so much the murder mystery, but the questions that arise afterwards that form this book. While the topic and the crimes are disturbing, I really enjoyed the book. I find it's a theme that often comes back in their books, and it is one of the reasons why I like to read them.
