I was interested in a book about the early days of space travel and the idea that there could be advanced humans on another alien planet. This wasn't something as hard to get going than that. It just rambles from one uninteresting character after another, with no real plot! If anyone wants to read truly interesting sci-fi stories of this period without all the gore or gorey sex, check out Arthur C. Clarke, Robert Heinlein, H. Beam Piper, or other really good authors. Not even worth buying at half price.
