This is another one by S.L. Viehl. Just like Blade Dancer it's in the same universe, but has different characters. The main species in this one are the 'Zangians who are aquatic. The whole idea of pods and a lack of property and a quite pragmatic view of life/injury/death. It's a very different way of looking at the world, from the perspective of a dolphin-person. Lots of inter-species stuff too, I love the way Viehl writes aliens! And I have to say, I was quite attached to the main character by the end of the book.
