Mary Poppins Comes Back by P. L. Travers, 268 pages

Pulled down from the clouds at the end of a kite string, Mary Poppins is back. In Mary’s care, the Banks children meet the King of the Castle and the Dirty Rascal, visit the upside-down world of Mr. Turvy and his bride, Miss Topsy, and spend a breathless afternoon above the park, dangling from a clutch of balloons.
