Query: Polar Bears Past Bedtime

This book is about two kids that go on trips to a whole different place in thearctic. It is like they are going back in time. My favorite part was when Jack and Annie did what they were supposed to do. My favorite character is Annie because she loves animals and I do too. I recommend this book to people and kids who like fictiion because all Magic Tree House books are fiction.
