The Master Key

Read by Judy Bieber

(4.3 stars; 69 reviews)

The Master Key was one of Baum's earliest full length fantasy books for children, published in 1901 just one year after The Wonderful Wizard of Oz. The protagonist, Rob, while experimenting in his workshop, accidentally summons up an electrical fairy who presents him with electrical devices so advanced as to seem magical. His gifts include a flying contraption, a stun gun, and something resembling an omniscient portable TV set. Rob travels the world, rendering assistance to European heads of state and narrowly escaping disaster at the hands of “primitive” cannibals, Turks and Tatars, pirates, and evil scientists who try to steal his inventions. It's great fun, despite the occasional use of racial stereotypes that reflect the values of its time. (3 hr 40 min)

Okay book, okay recording

(2 stars)

Having read much of Baum's other work, I was a little disappointed in this book. The protagonist is far less sympathetic than Baum's other child heroes. He lacks common sense, and his bumbling seems to satirize society's inability to use technology wisely. The racist stereotypes are vicious (and too pervasive to be easily edited out). If you enjoy children's literature of this time and can stomach the racism, you might get more out of the book than I did, but in general I wouldn't recommend it for children. The recording quality is fine. I found the reading a little stiff, but clear.
