Ann M. Martin writes children's fiction about friendship, family, school and the practical responsibilities of growing up. The Baby-Sitters Club begins with Kristy's Great Idea, in which Kristy Thomas and her friends create a babysitting business that becomes the framework for stories about changing families, illness, school problems, arguments and new relationships. Different books shift viewpoint among club members, giving the long series a strong ensemble structure. Martin also wrote A Corner of the Universe, a more serious standalone about a girl whose uncle returns to the family during one transformative summer, and Rain Reign, about an autistic girl searching for her lost dog after a storm. Her books are accessible and character-led, with everyday problems treated seriously from a child's perspective. Kristy's Great Idea is the essential start for the Baby-Sitters Club, while Rain Reign suits readers looking for a self-contained middle-grade family story. Read more Less
