Mary Poppins in the Park
The fantastic adventures with Mary Poppins continues in this book with a story of the Swineherd and the Goosegirl, reuniting a hunter and his lion friend, dancing with shadows, a visit to a planet with talking cats, and much more.
The sweet and amiable Mary Poppins portrayed in the movie is very different from the strict and stern Mary Poppins in the book, but the books have many more adventures, and Michael and Jane are never sure whether they really happened or not. Mary Poppins never explains, of course.
