This was a fantastic psychological thriller! It follows the story of two secondary school teachers in Hong Kong who are forced to switch from teaching in Cantonese to Mandarin or else they’re going to get fired.

Despite that the main characters are unlikeable, I was so stressed for both of them. The book was just so well written, and I found it difficult to put down. There was lots of office drama and bullying going on, and the characters were so vivid.
