Underground Alien Bases: Flying Saucers Come From Inside The Earth!
"Before I read this book I had no inkling  that there was so much UFO related happenings going on right under our feet, underground. Now I have come to learn that there are alien bases all over the planet. The stories may seem bizarre and unverifiable, but this book has convinced me otherwise. Especially, the account by Christa Tilton who apparently was taken to the underground base at Dulce, NM." --Tim Swartz, Conspiracy Journal
