I really like how the publisher is laying this book series out. Yes it is about whales, but it encompasses their entire world. Who do they see on the shore. What are some interesting bits about the grizzly and the black bear. They have amazing pictures, and often info bits not normally found in this level of a book. Periscoping was something I had seen, but never heard about until reading this kids book. These are really well done and great for any library collection.
