The Kzinti is a tiger-like alien race of warriors from the planet Kzin. They may look a bit like Aslan from Traveller, but they are not Aslan. The Kzinti males are intelligent but the females are not.
The first story is about the first meeting between the Humans and the Kzin. It doesn’t end well for one of the races…
The second story is about a Kzinti base at an old metal-poor star racing through the galaxy. The interesting thing about this story is that these old stars really exist. However, the story felt like it was set in a sandbox, to not upset the canon of Larry Niven’s work.
The third story is even worse. This is a sandbox. The human hero is stuck in some kind of zoo that was built by some kind of ancients.
But even though two of the stories are set in sandboxes, I enjoyed reading this book by three great authors.
