I want to start by saying this book is EXTREMELY well written. The world building is quite impressive.
Fictionalized Earth to fully fictional Dolvia (which seemed to strongly resemble the Middle East) were both well described and believable settings. The sci-fi elements, such as the reptilian gualareps are also well planned and executed, and not just inserted to fit the genre.
It’s quite masterfully written, with interesting characters, foreign social customs, and lots of social tension. Read full review.
