A new Librarian is appointed to run the Library, a bold decision at a time when school librarians were few and far between. The new Librarian soon comes up against resistance to her appointment, and there is conflict with the Library Prefect, who had responsibility for much of the old library. A dramatic resolution to the stand-off ensues during the half-term holiday expedition...School prefects organise a swimming gala in the new swimming pool, and water polo is introduced as a regular fixture. This book will appeal to all fans of the Chalet School series.
