I simply could not put this book down. It did what every good thriller should be able to do -- transfix you and make you want to turn the page to see what happens next. It was the twists that kept me reading this book. However, they are not so frequent that you expect a twist at the end of every chapter. There are just enough thrown in to make you reconsider every time you think you've sorted out what is really going on.
Reading the other reviews posted here, I was a little concerned about all the flashbacks that this novel uses. But upon reading the book I found it no problem at all. It is not overdone and they are all contexualised with modern day events. One will have no problem at all keeping track of things.
I was glued to this novel for the better part of a day, reading it in very quick time. I simply had to find out what was going to happen next! If you like that in a thriller, then you will greatly enjoy this novel.
