I remember how difficult it was to find great books for kids once they’ve moved to chapter books but are not quite ready for Newbery books.
Dragons and aliens and dinosaurs, oh my! And for girls, there are interesting slightly mischieveous girls to meet as well as cousins who are really sweet. Short chapter book series can often have repetitive plot lines about nothing or language that is neither rich nor interesting. There is something special about each of these book series for the child AND the adult reading along.
