When her family outgrows their well-loved rag doll, they donate Sally Ann to nice Mrs. Foster's day care center, where she overhears a conversation intimating that the center may have to close. Anxious not to lose her new home, Sally Ann resolves to save it, persuading the other toys to help by reminding them that they'll be able to come alive only at night if they're loved during the day. Together, they unmask the unscrupulous real-estate developers who have posed as state inspectors and preyed on Mrs. Foster in hope of buying her house cheap. Upbeat and imaginative, an easy chapter book that should find many readers; Sims's frequent b&w drawings nicely capture the warm ambiance and perky humor. Marred by see-through paper.
