This is a great way to finish the nine-novel run. While I didn't see the solution to the genocidal alien problem coming, it is perfectly fitting and lines up with the characters and the information about the science (such as that is).

The hunter Tanaka was a great new character, with a good balance between psychotic evil and explanation for why she was that way.

Amos remains one of the most reliable characters to ever live in print, and I very much appreciated his arc in this book.

There's no way to talk much about the story without some major spoilers, but it has battles, pathos, sacrifice, bravery, giant alien brains spanning light years, and a really nice epilogue.
