The Rings of Kether (15), paperback Fighting Fantasy gamebook, by Andrew Chapman
“A dangerous undercover mission on a wild and lawless planet!
Corruption is rife in the Alpha Cygni system and the flow of the illicit narcotic Satophil-d from the spaceports of the planet Kether has grown to enormous proportions.
Several attempts have been made to crack the notorious drug rings of Kether, with no success. Now the Galactic Federation has entrusted YOU with this dangerous undercover mission in this wild and lawless place. But will YOU succeed?
Two dice, a pencil and an eraser are all you need to make your journey. YOU decide which way to go, which dangers to risk and which enemies to fight.”
The adventure sheets in both of the VERY GOOD copies are unused.
In the GOOD condition copy, the character sheet has been used, but the pencil marks have been erased, and there is a name and address in ink on page 5.
