Hugo Galvéz was once the smartest man in Known Space. Now, he’s the smartest “Tin Man” -- a formerly biological person uploaded into an artificial brain and body -- in Unknown Space. Along with his gynoid companion, Murphy, he has been exploring the Universe, charting and recording star systems and galaxies for the adverturers and settlers to follow. Until one day they failed to return from a mapping mission. Hugo and Murphy found themselves restred from “back-ups” by the young Eithne Lamdagan, the 7th-generation gran-daughter of their oldest friend, Alyss Roaz. Naturally, they are very interested in finding out what happened to their predecessors in Galaxy S257163185. When Hugo, Murphy and Eithne venture into that far away galaxy, what they find is far more unexpected, and dangerous, than they could have imagined -- yet strangely familiar, Worse still, a very dark episode of Hugo’s past returns to haunt him. 186 full color pages of sci-fi action.
