The book is full of fascinating information about marbles, but this is secondary to a fast-moving story with good characterization. I cannot emphasize enough how much I, a passionate marble collector, enjoyed this story. It really conveys how, once-upon-a-time, a children's world revolved around these beautiful orbs that I now enjoy collecting so much. I shared Tip's excitement when he found an old cigar box of marbles belonging to his friend the magician - A bear sulphide, an onionskin, a peppermint swirl, Chinas, Commies and the "Shining Shooter" - a realie agate! Tip goes on to win the tournament and it was as thrilling as if I had been there myself. If you are passionate about marbles, this book will only serve to make you more so!
