On a Red Station, Drifting - Aliette de Bodard

The description makes you think that this book is mostly about the "Honored Ancestress" and her failing mind ship powers, but really 90% of this book is basically a fight between Lihn and Quyen because Lihn wants her respect and Quyen wants to be respected. Then there are some family issues that happen on Quyen's side, and did I mention the character flood.
The characters have mem-implants so they can call up their ancestors, and believe me, the author loves to take every opportunity to name drop them. So much I was confused who was a real person and who was an ancestor.

So basically the whole Honored Ancestress part of this book takes up about 10% and is magically solved right at the end, the rest of the book is familial in fighting.
