Question on the ending of "Cyteen" by Cherryh

It’s interesting to compare that first Chanur book ( Pride of Chanur, published in 1981 ) with the last ( Chanur’s Legacy, 1992 ). The aliens are much better developed in the latter, with the “evil” Kif having become the main backing of the Chanur power structure.

Like mentioned, she does reuse ideas and themes :). Her very early Hanan books from the mid-1970’s used that same Japanese trope. Her Foreigner books are much, much better ( a couple of them are subpar, but mostly it is a solid series ) - but it is a bit amusing to see her to replay that obvious fascination.
