Finished Mary Poppins Comes Back by P. L. Travers. This is the second book in the series. Mary returns, via kite, to again be nanny for the Banks children, which now consist of not only Jane and Michael, but twins Barbara and John and the soon to be born Annabel. Mary is as prim and stern as ever, but orchestrates all sorts of unusual adventures. Travers' Mary is much harder, much more severe than Disney's version of the character, but that's what makes her so much more fascinating, especially to the children.
