'Tom Swift in the Land of Wonders' Summary

Professor Bumper, introduced in the previous volume, 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.
