I thought this was a really easy read as the chapters were short and the wording was quite simple so it was a good one for when my brain was tired! I thought the sister dynamic was really interesting and the poor big sister having to deal with the spoiled little sister was very realistic. I enjoyed the portrait of the little sister and how she had many sides and managed to make every one believe her different version of events. A true psycho with no remorse. I got a bit confused at the end o the book but all in all the middle section was my favorite. I loved the twist towards the end of the book with the DR having to act fast and save himself. It was strange to say but i also found this book quite funny.
