The last book of trilogy hat series from klassen. Two turtles found a hat. Two turtles and one hat. How do they share it? Should they share it? Maybe this book wanys to convey about sharing or maybe not. You can share or you can leave the thing. The turtles in this book is so simple that child could draw it too. My kids really love this book because they love klassen's turtle illustration. So, we love klassen.
