Truly fascinating by virtue of it's focus on the prior works "villains". These are handled with tremendous detail and insight into their culture, birthed out of their unique extra-sensory physiology; a compelling metaphor on euthanasia and the right to die, coupled with thrilling narratives on the ongoing stalemate of a war with the humans. Ends on a brilliant cliff Lhanger, setting up not only for the conclusion in "Legacy", but the core MISUNDERSTANDING that threatens to destroy them both.
