This is my second favorite Magic Tree House book, because the book makes me think of my cabin when it is snowy. I also like polar bears, because they're white and pretty. They match the snow too. In the story, I was glad that the polar bears were nice, instead of mean. It is always nice to read about helpful characters.
I would recommend this book, because I learned that if you got stuck on thin ice, you get down on your stomach and crawl. I could use this information later on. Also, this book has riddles and I enjoy solving riddles and I am sure you will too.
