Polar Bears Past Bedtime
Mary Pope Osborne, Sal Murdocca
Jack and Annie are off on another adventure, this time to the Arctic. They make some furry friends and even get to see the mmagical Northern Lights, but can they solve the last riddle in order to become Master Librarians? They’d better hurry, though, for it’s getting colder by the minute.

I would recommend this book. I enjoy reading Magic Tree House books.

I didn't like this book as much as the other ones. I love the Arctic so I liked the setting but not the story. I would sort of recommend this book.
