There's enough genuine feeling in this realistic story to make a miniature novel. Rosie is sad and anxious because Grandma is in the hospital and Rosie, at eight, is too young to visit her. Friend Kate helps dress Rosie in hat and gloves in the hope that she will pass for ten; Rosie equips herself with flowers and braves the hospital. But when a hospital guard questions her age, her confidence is undone; quickly handing the elevator man the flowers (""for Grandma Mice on. . .seventh""), she flees. Happily, when Grandma finally does come home, it turns out that she did get Rosie's carnations, and still has them, neatly pressed--a message of love received, valued, and understood. Keller's simply drawn illustrations, their sparse details harmoniously arranged, are a nice complement to her warm, satisfying story.
