"It all starts when Mary Poppins is blown by the east wind onto the doorstep of the Banks house. She becomes a most unusual nanny to Jane, Michael, and the twins. Who else but Mary Poppins can slide up banisters, pull an entire armchair out of an empty carpetbag, and make a dose of medicine taste like delicious lime-juice cordial? A day with Mary Poppins is a day of magic and make-believe come to life!"--Provided by Goodreads.com.

With a boom and a burst of fireworks, Mary Poppins returns, falling from the sky like a shooting star. She arrives not a moment too late: The Banks home is a complete shambles--five wild children without a nanny are five children too many!

For each letter of the alphabet, there is a one page description of a character or incident based on the other Mary Poppins books, which contains the letter in question appearing many times at the beginning of words.
