It's book you can finish in one sitting. It's a good read as it has a lot of things going on and had some really nice cocktail of predictable and unpredictable twists.
The book gave a deeper angle from a psychological aspect and making the readers understand what is the difference of pain and fear.
The protagonist showcases, self belief, and the curiosity which drove her out of her underlying emotions.
With an end which asks for more, I definitely think you can go ahead and read it if you love investigation, thriller, psychological thriller and finding your self worth.
