The Children's Hour by S. M. Stirling and Jerry Pournelle 1991
The fastest way to get ahead in Kzin society is to cut through the endless challenges and duels to the death and take on your father.
But Chuut-Riit, Planetary Governor of occupied planet Wunderland, is teaching his kits a new way--the way of the humans. And the humans don't like it, at all. Expanded from parts of Man-Kzin Wars II and Man-Kzin Wars III.
