Johanna Hurwitz, the author of more than 70 popular children's books, began her career as a children's librarian working for the New York Public Library as well as school and other public libraries. Married and the mother of two grown children and grandmother of three, Johanna says that many of her books have grown out of family life or observations made during her library work. Her first book was Busybody Nora and it gradually grew into a series of fourteen books about city kids living in an apartment building. Nora and her brother Teddy as well as their neighbors Russell and Elisa interact with their neighbors and their city environment. Because they live near and play often in Riverside Park, this series was eventually named "The Riverside Kids." Each book is made up of six self-contained chapters which can be read individually or together.
