This book was 75 - 100 pages too long. I found it became a little repetitive near the end of the book. The ending was pretty underwhelming, but I did enjoy the descriptions of the hiking and camping. The first half of the book dragged for me, but at halfway the tension definitely increased and it had my attention. 

I know this is translated from Swedish, and I feel this could have gone through another round of editing. My edition had some grammatical errors and typos scattered throughout.

The map at the beginning has spoilers in it for what happens to some of the  characters, and I wish the mountains were labeled on the map.
