Visitors from Oz
the wild adventures of Dorothy, the Scarecrow, and the Tin Woodman
Dorothy and friends return in this Oz sequel, this time to New York City, on the eve of the 100th anniversary of "The Wizard of Oz". Combining mathematical riddles with technological pyrotechnics and vivid suspense, Martin Gardner has created a new fable celebrating the power of imagination and the lure of an ageless heroine named Dorothy from the turn of the century.
