Books like The Compleat Enchanter

The Mathematics of Magic was probably the greatest discovery of the ages - at least Professor Harold Shea thought so. With the proper equations, he could instantly transport himself back in time to all the wondrous lands of ancient legend. But slips in time were a hazard, and Shea's magic did not always work - at least, not quite as he expected... This omnibus volume contains three episodes of the Magical Misadventures of Harold Shea: - The Castle of Iron (1950, novel)- The Mathematics of Magic (1940, novella)- The Roaring Trumpet (1940, novella)The stories in this omnibus were previously published as two books: 'The Incomplete Enchanter' and 'The Castle of Iron'.
