La llave maestra: un eléctrico cuento de hadas

Rob Joslyn es un niño que le encanta experimentar con la electricidad y durante uno de sus experimentos se produce un destello brillante y aparece un ser que se hace llamar el Demonio de la Electricidad. Éste le dice a Rob que accidentalmente ha tocado la Llave Maestra de la Electricidad y que tiene derecho a exigirle tres regalos cada semana durante tres semanas sucesivas. Rob protesta que no sabe qué pedir y el Demonio acepta elegir los regalos él mismo. Durante las semanas siguientes, Rob vive aventuras explorando el uso de los ingeniosos regalos del demonio, que anticiparon en décadas varios inventos.
Al igual que algunas de las novelas para adultos de Baum, La llave maestra nos presenta encuentros con figuras históricas reales de la época, como el rey Eduardo de Gran Bretaña, el presidente Loubet de Francia y el duque de Orleans .

Lyman Frank Baum was an American author best known for his children's fantasy books, particularly The Wonderful Wizard of Oz, part of a series. In addition to the 14 Oz books, Baum penned 41 other novels (not including four lost, unpublished novels), 83 short stories, over 200 poems, and at least 42 scripts. He made numerous attempts to bring his works to the stage and screen; the 1939 adaptation of the first Oz book became a landmark of 20th-century cinema.
Born and raised in Chittenango, New York, Baum moved west after an unsuccessful stint as a theater producer and playwright. He and his wife opened a store in South Dakota and he edited and published a newspaper. They then moved to Chicago, where he worked as a newspaper reporter and published children's literature, coming out with the first Oz book in 1900. While continuing his writing, among his final projects he sought to establish a film studio focused on children's films in Los Angeles, California.
His works anticipated such later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high-risk and action-heavy occupations (Mary Louise in the Country), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).

Un libro breve pero interesante sobre las aplicaciones de la energía eléctrica y los peligros que conlleva.
Es evidente la formación teosófica de Baum.
