Tom Swift (in the 2nd series Tom Swift, Jr. ) is the central character in five series of books of American juvenile science fiction and adventure novels that emphasize science, invention and technology. First appearing in 1910 the series total more than 100 volumes. The character was created by Edward Stratemeyer, the founder of the Stratemeyer Syndicate, a book-packaging firm. His adventures have been written by different ghostwriters over the years. Most of the books are published under the collective pseudonym of Victor Appleton. Tom Swift In The Land of Wonders, or, The Underground Search For the Idol of Gold, is Volume 20 in the original Tom Swift novel series. Professor Bumper is on the trail of another lost city, this time the lost city of Kurzon, somewhere deep in Honduras. The Professor has come into some documents which he thinks will help him locate the city, and the documents make mention of a huge idol made of solid gold. Professor Bumper would very much like Tom Swift to accompany the expedition. As circumstances would have it, Professor Bumpers rival, in the form of Professor Fenimore Beecher, is also on the trail of Kurzon. Unfortunately for Tom Swift, Professor Beecher is also trying to win the heart of Mary Nestor, Tom Swift's sweetheart! Envy, rather than fame or fortune, drive Tom to finally accompany the expedition to Honduras, as Tom hopes to prevent Professor Beecher from discovering the idol and presenting some of the gold to Mary Nestor as a betrothal gift.
