I like the adventure of the story and all the wonderful culture of Norway- the towns, the food, the dancing, the music- and the insight into how other countries were affected by WWII and how the families rebuilt their towns and culture. I found the characters realistic and like-able, especially how one girl begins shy and gradually finds her voice. The adventure/mystery kept my guessing and was enjoyable.
What I did not like: Plot holes, stereotyping, and a lot of the story hinging on someone jumping wildly to conclusions based on zero evidence and taking drastic action based on a "strong feeling." Also I was unpleasantly surprised to find prejudice, fear, and hatred towards a person (because he has a scarred face and is a foreigner) is justified by the story. Especially odd because the main characters experience prejudice from others and express how much it hurts. Because justifying and normalizing prejudice is such a big part of the plot, I would not have reprinted this book.
The Tangled Skein could be a good book club discussion or study of an essay because it brings up great topics to talk about (prejudice, critical thinking, role of women, courage, grit, vision).
