My favorite part of the story is when Jack and Annie go to Antarctica. This is my favorite part because when they get there they get to wear sealskin. I also liked how in the book Jack and Annie get to do things like a polar bear would. It reminded me of when my sister and I played a polar bear game where we both weighed 4,000 pounds. Reading this Magic Tree House book made me want to read even more of the series. I imagined myself going on adventures with Jack and Annie and thought it would be great fun. My favorite character is Annie because she is very adventurous and somehow knows what animals are saying. I bet if you read this book you would like Annie too!
I recommend this book to people who like polar bears and mysteries. I recommend it to people who like polar bears because this book is mostly about polar bears. I think people who enjoy mysteries will like this book too because the book is about two kids that solve a riddle. It is a great book. Read it!
