Less of a thriller than I expected and more of a literary fiction about psychological torment and revenge. I really loved the format and how each chapter builds on the one before. It's very repetitive but I didn't mind because that was the point, to be able to see the situation from many different points of view.

Reminded me a bit of Lemon by Kwon Yeo-sun but this is much darker and more cohesive.

The constant twists really leave you guessing and it's been a while since I've read a book that had my jaw dropping with each new piece of information we learn.
