Six-year-old Miranda is considered an odd little girl, in part because of her insistence that she has invisible friends. (Her costumes, with too-long sleeves, bumble-bee jewelry, and pipe-cleaner feelers probably add to that impression.) Her mother worries about Miranda's over-active imagination, and her over-zealous eating habits. A misunderstanding leads Miranda to believe that her spirit friends have been permanently removed from her life. As an adolescent, Miranda struggles with day-to-day life. Although she has no idea why, she doesn't fit in at all with her peers. Lacking the comfort of the spirit friends of her youth, she has become a rather unimaginative and morose child. As an adult, Miranda thinks of adolescents as nasty little creatures who are to be avoided at all costs. Unexpectedly, she meets a child who changes all that, and who has questions that set them on the path to regain what they thought they had both lost. Adult Miranda discovers that, just like tonsils, other very important things may sometimes "grow back."
