Invitation to the Ballet by Katharine Holabird
Imagine Angelina's delight when she wins two tickets to the gala performance of Cindermouse...and then her disappointment as friend after friend has received an invitation to something else that day. At the last minute, however, Angelina is called by the Royal Ballet's director to fill in for an injured ballerina and she gives her two tickets to her parents. There are six envelopes in all with cards and letters to open up and read as well as a special lucky star pendant in the last envelope.
