(Location 248 of Kindle version)...sex and time are non-refundable.
I think the author has mentioned an important fact through this sentence. I am not quite sure about sex since the experience and the perception can vary from person to person (I am not sure whether Zia felt like sex was non-refundable, though she really felt like that about time), but it is true regarding time.
I think many of the victims of the psychopathic killer proved that sex is non-refundable, and they had to pay with their lives proving that time too was non-refundable as well.
Do you agree with this statement, fully or partially? Why? How did the author relate this to his story?
The topic is about the book, so the second question MUST be answered as well (the mod).
