The Trimoni Twins and the changing coin

Beezel and Mimi Trimoni are eleven-year-old twins and magicians. They love doing tricks, but what they love even more is ka-poofing: real magic that allows them to change people and animals into other animals. Only they have this gift, through the power of their amazing and unique Changing Coin. The girls are thrilled when a mysterious magician, The Great Paparella, challenges them to a magic duel at the famous Merlin Hotel, but they both feel that there is something threatening about him. Could he be after their coin? Adventures galore ensue and ka-poofing magic reigns as Beezel and Mimi go on a wild ride to save the changing coin from changing hands.
