Incredible -- the third book in the Books of the Raksura, this is definitely the best one so far.  I cannot give five stars enthusiastically enough.  This is more emotional than the previous book, and the characters in multiple Raksura colonies are really well developed.  While the novel concludes in a way that doesn't read like a cliff-hanger, I cannot wait to read more. 

Note: This is the third book in a series comprised of 5 novels and two collections of novellas/shorts.  The prior novels are required reading for this one.

Content warnings elaboration: cannibalism can only be described as 'of a sort?' (there are no humans in these books); one species attempting to capture individuals from another to forcibly breed with them is a theme throughout this series
