My Kid’s Favorite
Format: Hardcover
This is a favorite in our house! Even the adults enjoy reading the National Geographic versions of 5-minute stories. The facts are actually interesting, and we read them again and again! Great for science minded kids.

Nice Book!
Format: Hardcover
Nice thick book, beautifully bound. Spectacular artwork. Easy read, good for a beginning reader, too. Lots of interesting shark facts. Good for a shark lover. Makes a fantastic gift when paired with an underwater jigsaw puzzle or something like the National Geographic Shark Excavation Stem Kit. Suitable for a variety of ages; preschool to grade 3. Sound purchase.
