"Sir Sidney s Circus is the best in the world. But who s the star of the show? The Circus Times is having a contest to find out. Just thinking about it gives Sir Sidney a worrywart, so he goes off to rest. Soon Elsa the elephant, Leo the lion, and the other performers are thinking more about winning the trophy than putting on a good show. Meanwhile, ringmaster-in-training Barnabas Brambles needs some help running the circus without Sir Sidney, so Bert and Gert, the mice who travel with the show, write a book to teach him how it s done. Does Bert and Gert s plan work? And who is the star of the circus?"--From publisher.
