The sheer physiology of this story is mind-blowing! That and the fact that never before had I thought about this nomadic people who live with Reindeer (Santa's village excluded)- the Lapps. (Though the author gets low marks for cultural competency since they come off as, essentially, subhuman.)
I had trouble connecting with this book fully though. I got it as a kindle daily deal, and the ebook has all of the pictures at the end and I wish I had seen them earlier- it may have helped me picture this totally foreign landscape.
