Excellent idea, well realised. Great pace as always. ( )

I'm not really being fair. The book was written in 1969 and Larry Niven's later world building in Known Space and Ringworld was so enthralling that perhaps I expect too much. This was a re-read (or so my partner tells me) but I remembered very little about it. My main problem is not that it has dated badly because it hasn't. The problem is with the writing and structure. Most of the book feels like it is about people getting from A to B or to the end of the corridor and back and it's just not very interesting. If that had been pruned out it might have made a good shorter story. ( )

Another good story by Niven. Old fashion space opera. A future distant colony still gets occasional shipments from Earth. It has developed into a 2 class dictatorship. Changes are coming from within and New tech from Earth also has implications. Time for payback. ( )

Niven has created a society , a police state which is heavily dependant on organ transplants for treating even trivial ailments. the rewards of the system are almost entirely lavished on the police, with small rewards for their collaborators. A mutant, with curious mental powers and the arrival of a cargo ship, upset the applecart. ( )

Interesting view of how a sudden new technology can drastically alter the status quo. Enjoyable, but more action-adventure than needed, and less careful thought than required. ( )
