"Another Wildside paperback original, continuing this new series collecting the early pioneering pulp magazine novelettes of John Russell Fearn, presenting the first-ever reprinting of ""Earth's Mausoleum,"" ""Metamorphosis,"" and ""Dark Eternity."" Three stories of soaring imagination, lost gems plucked from the pages of the pre-war issues of Astounding Stories during its ""thought-variant"" revitalization. ""Earth's Mausoleum"" tells of interstellar visitors to Earth who seek to advance human civilization by conferring the benefits of their great science, but instead bring Earth to the brink of disaster. ""Metamorphosis"" explores the terrifying aftermath of an ill-judged scientific experiment that destroys its creators and all life on Earth, and ""Dark Eternity"" is a fitting capstone to Fearn's ""thought-variant"" period, in which he destroys the entire universe!"
