Let me tell you, it was a Herculean effort of will to stop after just one chapter every day. I did end up finishing a day early, since I know Christmas will be busy for me. 25 Days is a super cool concept - a book that is also an adventure calendar. Per Jacobsen keeps the tension high, using this format. The story was pretty good, but man, that family made some CHOICES. Nevertheless, I had a lot of fun with it 3.5 stars
