L. Sprague de Camp
Lyon Sprague de Camp (1907–2000) was an American science fiction and fantasy author. His writing career spanned over fifty years. He wrote novels and works of nonfiction.
This omnibus edition contains all three volumes of the magical misadventures of Professor Harold Shea – The Incomplete Enchanter, The Castle of Iron and Wall of Serpents.
The Mathematics of Magic: the greatest discover of the ages... at least, that's what Professor Harold Shea thought. With the proper equations he could instantly transport himself and his friend Reed Chalmers to other times, to visit the wondrous lands of ancient legend.
But Shea's magic did not always work – at least, not quite as expected. A dragon spell might result in a hundred dragons or, even worse, one tenth of a dragon. And the imaginary lands to which he traveled, from the Castle of Otranto to the Norseland of Odin and Thor, held countless dangers that not even Professor Shea could predict.
