Book excerpt: Emma loves lizards and pirates and cowboy boots, so when a package arrives from Uncle Leo, she doesn?t know what to do with the ballerina costume inside. ?I don?t know how to be a ballerina,? Emma says. She flops when she should float, she trips when she should twirl, and her music sounds like burping! But when she decides to make her own rules about how to be a ballerina, Emma?s style prevails in her triumphant dance debut.
