I didn't read the whole book.
I couldn't.
I just read whatever is available on Google. About a few pages.
I feel for the woman and everything she went through.
I don't know whether she did the crime she was put in jail for or not.
Jail is no place to be for sure.
But from whatever I read I think it to be made up to a certain level. I mean a lot of it, not all. The incidents and stories mentioned in the book sound filmy and cooked up for the reader's interest I think. They've been directly taken from shows on Netflix and Indian movies. I would elaborate more but I request to to read whatever is available and then decide for yourself.
