In the last decade of the 21st century, advanced biotech and interplanetary colonization have transformed our solar system into a setting as exciting and alien as any interstellar empire. Pirate spaceships hijacking black holes . . . sentient computers and artificial "bioroids" demanding human rights . . . nanotechnology and mind control. Transhuman Space is the corebook of the new "hard" science fiction series created by David Pulver and written by the top GURPS authors.
