Retief: Envoy to the New Worlds — Keith Laumer

Between the lines of the official histories of the frontier worlds of the 29th Century lie a myriad confidential accounts of the boners, near-catastrophes, and interstellar crises that were bound to occur when human meets non-human. The adventures of the interplanetary diplomat Retief loom large in those highly classified reports. They also loom large in the eyes of devoted science-fiction readers because the cosmic tight-rope diplomacy of Retief compose a body of science-fiction adventure guaranteed to be astounding, amazing, startling, galactic, weird, and thrillingly wonderful. ENVOY TO NEW WORLDS was the first book to present Retief's adventures to the s-f public.
