This is one of the best thrillers I have actually read so far, it beautifully challenges the psychological state of every character and somehow you are also left with challenging yours. The way it takes about psychology makes it actually very easy to understand the whole concept and even what must be going on in the mind of Alecia and Theo himself. Indeed a very beautifully written book however to my personal opinion the final stage of the book needed more space in the book, it would have been better if we have more on the thoughts of Theo as he was revealed to be the main person behind all that mess.
Nevertheless its a very good book to kick of your psychic personality.
