When i was in junior high I found this book at our public library. I stayed in the car reading it while my mom went in the mall, and stayed up all night reading it. (I told my mom I was sick the next day, so I could stay home). I was certainly too young to be reading some of this book's content at that tender age.
Recently found a copy and reread it, and it was just as great as I remember. You ARE there with the carnival and its colorful atmosphere.
Highly recommend this book...just not for an eleven-year-old kid.
