My boys are sports fanatics and love dinosaurs and they absolutely LOVE these books. We have read each book - hockey, soccer, baseball and basketball each many many times and have football on order. I am even buying a set for my school library! I love these books because they are fun to read, have great pictures and have an easy rhythm which is nice for bedtime stories. My oldest even has a couple of the books memorized! I LOVE these books, buy them, you won't be disappointed.
