The Monster's Ring: A Magic Shop Book

*Twist it once, you're horned and haired;* *Twist it twice and fangs are bared;* *Twist it thrice? No one has dared!* Russell is sure that the ring he gets at Mr. Elives' shop is just a silly magic trick, but he follows the instructions and twists the ring twice anyway-and becomes a monster! Includes an author's note.
