I read this thriller in two days (or rather two nights). One of the best I've read in a long time. It is one of those books that I wanted to cheat and read the last page -- but didn't want to ruin the ending. Couldn't read the book fast enough -- yet wanted it to last longer. Who we are makes us more believable even if we aren't who you think we are. It truly is an absolutely gripping psychological thriller. I rate my books out of 10 and this one is a 10+.
