Babes in Beijing by Rachel Dewoskin, and more importantly När rött blir svart by Qiu Xialong (don't know English title, not important since original language is Chinese...). The latter is a detective story y'see. And just noticed that it's published by editor friend's publishing company. How handy! *starts plotting bribery tactics*
Edited to say that Qiu Xialong writes in English, so title in English is When Red Is Black, and I'm an idiot, and now I need it in English.
