Nina Borg works with refugees in Denmark - both those above and under ground - and she's used to emergencies. She lives a large part of her life in a world that other Danes seldom see, even though it's right next to us all the time. It is a world where blackmail, trafficking, abuse and unnecessary death is part of every-day life; a world where children disappear every day without anybody asking any questions.But Nina cannot close her eyes to people's plight. When she finds the boy in the black suitcase, she tries to discover who he is, and where he came from. She won't let him be part of the statistic of children who just disappear.That turns out to be a life-threatening decision.I wavered between 2 and 3 stars for a long time. It has taken me forever to get through this book, and I contemplated giving up on it several times, but while I had no particular desire to pick it up for long stretches of time, when I actually did pick it up, I was intrigued by what I read. I think in the end I read this in 3 or 4 sittings... but with a couple of weeks between each. The plot is thrilling and supposed to keep you at the edge of your seat... which it also manages to do most of the time. But every now and again the main character just makes a decision so mindnumblingly stupid that I felt like throwing the book aside in disgust. If you find a person brutally murdered, call the police! Don't just walk around the house, leaving blood and fingerprints all over the place and then run away, dropping your mobile phone in the process - that's just plain stupid!Fortunately the second half was a lot better than the first - both in terms of plot and in the lack of stupid decisions made, so at the end of the day I enjoyed it more than I had at one point thought I would, and I'm glad I stuck it out. So 3 stars it is - as well as a determination not to read any more books in this series. While well written, they're just too unpleasant.
