The second book:

 

Kwaide is the second book in the Ammonite Galaxy Series, following on with the same characters from Valhai. It is set in the same binary system, as you can see from the plan of the system at the top of the page.

Kwaide is the name of the planet where Six was born, and where he became a no-name. The book tells the story of what happens when he and Diva are let loose on an unsuspecting system. There are quite a few surprises right through the book, and the banter between the characters goes on.
