Great-uncle Matthew, G.U.M. for short, collects fossils. He happens upon three rare specimens in his travels—Pauline, Petrova, and Posy. Care for these new “specimens” falls to his niece, Sylvia, and her nurse, Nana. G.U.M. disappears for years at a time and the family finances dwindle. Pauline shows promise as an actress. Petrova loves anything mechanical, and as the title, Ballet Shoes, indicates, Posy was born to dance. Yet, lessons, school, and clothes drain the budget. What will happen to the Fossil girls and where is G.U.M.? Give Ballet Shoes by Noel Streatfeild a twirl.
