This is the story of Dorothy and her little dog Toto, who are carried away from Kansas by a cyclone and transported to the wonderful world of Oz. She meets three companions - the Scarecrow, the Tin Woodman and the Cowardly Lion - and the three journey to the Emerald City of Oz to ask the Wizard of Oz to give them their hearts' desires, which in Dorothy's case is to return home to Kansas. On their way to Oz and while fulfilling the tasks that the surprising Wizard asks of them they encounter witches, winged monkeys, the Deadly Desert, fighting trees and magic shoes. This edition is evocatively illustrated with the original drawings of W. W. Denslow which have been sensitively re-coloured by Barbara Frith, one of Britain's leading colourists.
Tenia quaranta-quatre anys quan es va començar a vendre El màgic d'Oz. Abans havia fet tota mena d'oficis, des d'actor teatral fins a corresponsal de diari. A Chicago, on va començar a escriure llibres per nois i noies, va inventar el personatge de la Dorothy. Era l'any 1987. Frank Baum va morir vint-i-dos anys després, deixant aquesta història que ha esdevingut un clàssic.
