3 Vintage Hardcore Sci-Fi Novels

This 3-novel compilation represents the best in hardcore science fiction from the golden age of the genre. This 338-page e-book includes Raymond f. Jones' classic "The Year the Stardust Fell," "Earth Alert" by Kris Neville and "The Secret of the Ninth Planet" by Donald A. Wollheim."

I hope you find them as thoroughly enjoyable as I did, a true hardcore sci-fi fan.
