The manager of Rainier Elementary School’s cafeteria. Mrs. Beatty is a gruff, no-nonsense woman but she has a kind and generous heart. Mrs. Beatty stands up to Henry’s school bullies and offers him the chance to work with her in Camp Harmony’s mess hall, which allows Henry to reunite with Keiko. Mrs. Beatty grew up helping her father aboard the ship he served on, and she considers her father’s best friend from that time, a Chinese man and fellow Merchant Marine, her uncle.
