This is the only book I've found which adapts the legend of Robin Hood in a child-friendly manner. My four year old, although he doesn't understand all the witty asides in the cartoon strip story, really enjoys listening to the story. It helps to answer the million questions he asks me about Robin Hood, although it throws up new ones too!
The story is presented in short chapters which makes it easy to dip in and out of, and the pictures have a wealth of detail which are good fun to sift through. Even my two-year old has been spotted looking through it on her own.
I think this book is probably aimed at older kids, but I would recommend it for anyone interested in Robin Hood. I am not actually very interested in him, but I still enjoy reading the book (just as well, as I have to read it every day!).
