SCARDOWN by ELIZABETH BEAR
I'll start with complaints.
1. If your book is written in English, if you use another language in same book make sure you have the English translation. I've seen this done before in many book I've read. It's irritating if you don't have access to the internet to translate sometimes whole paragraphs of dialogue.
2. When the POV changes, maybe list in the paragraph title whose POV it is or maybe "Casey thought. . ." so we have an idea who is talking. One chapter took me over 1-1/2 pages to figure out whose POV it was.
I loved the ending. The one man, two women (not lesbian) thing - I just couldn't imagine it working so smoothly. Overall, a good book/series.
