The writing is great. The world-building is intriguing.
The main problem is the lack of editing work. This book is close to 1000 pages long. This could have been stripped down to 400 pages and the whole book have been great. I mean the plot completely change at 50% of the book. I have read comments about the other books and it seems that they have the same problem. I think I will stop there with this series.
The depiction of women and LGTB is kinda of unnerving. The Lyuccu appear to be based on the Mongol invasion and are very one-sided.
