Plot introduction

The boys hunt for Prewytt Brumblydge, inventor of the Brumblitron, which is threatening to explode, destroying the Earth. This time, instead of journeying to Basidium, they fly to an airless rock named Lepton that orbits 1,000 miles above the Earth's surface. This novel introduces the fictional metal Brumblium, a greenish metal that shows as infragreen on a spectroscope and has twice the density of uranium.
