Another commenter said if the author made u angry they did a good job. Well I was upset with the ending but I will not give any spoilers. Some parts were far fetched but I was so enthralled and on my toes that I read this book in one sitting. Freida does a wonderful job of provoking your anxiety and having u grasping for more to go to the next chapter. I enjoyed the book even when I didn’t get the ending I wanted. At first I empathized with the main character and then despised the main character. So I have to say Freida has a talent for psychological thrillers I just hope her future books can become more realistic with the plot twists. Anyways I definitely recommend you read her work and this book was worth the money.
