Not going to give spoilers, but read this if you are thinking to read the book.
The book will hook you till chapter 20-25 something and then it will become monotonous and repetitive. Just questions and people blaming others. Nothing mind blowing.
But since you read half the book, you will force yourself to finish the book anyhow to know who is the culprit.
Again, since you are reading book forcefully, you may expect a mind blowing 'woah wth?' ending. But you'll be disappointed.
3 starts only for hooking me up for half of the book.
