The pacing is not the ONLY terrible thing about this book, pretty cheap novel, halfway through and I was already too bored to read it completely, especially all those forced to read past memories. Also there were many false alerts, mostly at the end of each chapter that felt pathetic how author tries to make you continue reading.
The only good thing is the ending. Almost the last 50 pages, where the twist comes, and it was truly admirable.
Overall, if it was half of what it is now, i would have rated 5 stars, but all those unnecessary and cheesy memories ruined it for me.
