World of Ptavvs

Kzanol was a thrint from a distant galaxy. He had been trapped on Earth in a time-stasis field for two billion years. Now he was on the loose, and telepath Larry Greenberg knew everything he was thinking. Thrints lived to plunder and enslave lesser planets . . . and the planet Kzanol had in mind was Earth!

About Larry Niven:
Born April 30, 1938 in Los Angeles, California. Attended California Institute of Technology; flunked out after discovering a book store jammed with used science fiction magazines.  Graduated Washburn University, Kansas, June 1962: BA in Mathematics with a Minor in Psychology, and later received an honorary doctorate in Letters from Washburn. Interests: Science fiction conventions, role playing games, AAAS meetings and other gatherings of people at the cutting edges of science. Comics. Filk singing. Yoga and other approaches to longevity. Moving mankind into space by any means, but particularly by making space endeavors attractive to commercial interests. Several times we’ve hosted The Citizens Advisory Council for a National Space Policy. I grew up with dogs. I live with a cat, and borrow dogs to hike with. I have passing acquaintance with raccoons and ferrets. Associating with nonhumans has certainly gained me insight into alien intelligences.
