This was my daughter's first Dora book, which we received as a gift for her first birthday, before either of us even knew who "Dora" is. My daughter fell in love with it and at 22 months, still asks to read it at times. She is now a big Dora fan. Basically, Dora is playing hide and seek with her best friend, "Boots," and on each page there is a flap to lift to see if he is there or not. I give it a 5 based on her enjoyment of it over the months.
