Kingpin Planet: The Golden Amazon Saga, Book 12

The Cosmic Crusaders are plunged into a strange new space, where all the probabilities of electronic law are strangely altered, a complete and stunning inversion of all so-called natural laws. They discover the mysterious silver planet of Tuca, and deep below its surface they find an enigmatic machine--the legacy of a vanished race. Masters of science, they had overreached themselves by constructing a strange machine that could alter the very laws of nature. But the machine had destroyed its creators, and blasted a neighboring planet into a cosmic cinder...and unless the Cosmic Crusaders can stop it, it may destroy the entire universe! Another epic space adventure of the Golden Amazon, John Russell Fearn's most famous and enduring character!
