Summary: A weak first novel, but explains a lot about Known Space
Review: WORLD OF PTAAVS was Larry Niven's first novel, published in 1966, and with its 2106 setting it is one of the first stories chronologically in the Known Space canon. It is clearly a weak work, and offers only hints of the wonderful ideas that Niven was to write about only a year later.WORLD OF PTAAVS begins two billion years before the present with the alien Kzanol, a member of the Thrintun race. This race had the ability to control others telepathically and are the Slavers mentioned in later Known Space works. After the drive on Kzanol's ship burns out, Kzanol puts himself into a stasis field and aims himself at Earth. He supposes that only 90 years will pass until he is rescued, but eons go by while he lies in stasis after impacting in Earth's ocean. In the near-future, a scientist believes that he can break open Kzanol's stasis field and enlists the help of Larry Greenberg. A telepath, Greenberg's job is to read the alien's mind for several seconds before the field is reactivated. However, Kzanol's telepathic abilities overwhelm Greenberg, and Greenberg comes to believes he is Kzanol. The two Kzanol's set out to Neptune, racing against each other to claim the telepathic amplifier that Kzanol sent there, with which one could enslave all of Earth. Lucas Garner, an agent with the UN, gives chase. WORLD OF PTAAVS was clearly written in the mid-60's. There is only one female character, and she is a stereotypical June Cleaver housewife. Niven was unable to foreesee the advent of powerful personal computing, and the computers of the novel output their information on paper strips like stocktickers. One amusing part of the novel for modern audiences is a reference to "West Berlin." Even the science of the story is outdated, one part refers to landing on Neptune, but Neptune is a gas giant without a solid surface. It is difficult to recommend WORLD OF PTAAVS, it is a very weak novel with wooden characters and clumsy writing. However, the novel is an integral part of Niven's Known Space universe, and much of the elements of this novel went on to play a part in other Known Space works. If you've never read anything by Larry Niven, though, get his collection NEUTRON STAR (out of print, several stories are in the collection CRASHLANDER), or his award-winning novel RINGWORLD. Check out WORLD OF PTAAVS only if you want light shed on certain elements of the Known Space series.
