Grade 1-4?A delightful story based on an article in the New York Times in 1952. Seven-year-old April idolizes her 15-year-old sister, Annabel, who can do almost anything but has trouble with math. The teen's teacher has given her one last chance to earn a decent grade by solving a particularly difficult problem. When Annabel cries, Who does she think I am, Albert Einstein? April's curiosity and compassion for her sister result in a surprising solution to the whole dilemma, as well as to the math problem. After doing a little research about the famous scientist's life, she decides to write him a letter describing her sister's situation. He responds in an unusual, but ultimately helpful way. According to an author's note, Einstein really did find the time to go over equations with children who asked for assistance. Barasch provides a refreshing mix of genres and subjects that will appeal to many readers. The nostalgic cartoon illustrations and numerous quotes from the international figure add charm to this enchanting tale
