Narrated by Josephine Bailey and Simon Vance. Bailey uses a high-pitched voice for her main character, which some might find annoying, but it worked OK for me. Vance uses a Chinese accent for his narration of the professor's diary, which annoyed me because it seemed inappropriate. (The accent itself didn't annoy me.)
This book is not for the faint of heart. Part of the story concerns the Nanking Massacre of 1937, but that's not the only gruesome stuff.
It's an odd book, part thriller (but subtly subverted - e.g., no "regeneration through violence" theme or "white people come into another culture and save everyone" theme), part mystery, and part historical fiction.
I had trouble believing in the motivations that drove Grey, the main female character, and trouble believing in the relationship between her and the professor (main male character).
But for some reason it kept me listening. I guess partly because I wanted to see where the author was going to go with the subtle subversion of the genres she was playing in.
