Ruby and Garnet are ten-year-old identical twins who do "everything" together. Especially since their mother died three years ago. At school the girls are known simply as The Twins. They dress alike, wear their hair the same way, and sit together in every class. In fact, "everything" about them is the same -- except their personalities. Ruby is funny and outgoing, Garnet is sensitive and shy. Together they're the perfect double act -- and that's just the way they like it.
Soon the twins' life is turned upside down. Their dad and his friend Rose buy a bookstore out in the country and the whole family moves. Ruby hates their new school, but Garnet thinks it isn't that bad. When Garnet becomes friends with some of their new classmates, Ruby feels betrayed and stops speaking to Garnet. Garnet misses her sister terribly but has to admit it's nice doing things on her own for a change. Somehow the girls will have to finda way to maintain their special twin relationship without spending every minute of the day together.
Both humorous and tender, "Double Act" is the touching story of two girls coming to terms with their own identities and learning that being independent doesn't have to mean being alone.
