This one was a fun "what the heck is going on" type psychological thriller. Fun may not be quite the right adjective, but considering how many times I changed my mind about what was happening, it became a game of sorts. It did take me until the second section to figure out the players since one of the protagonist is not named at the beginning. Once I figured out the players, while it didn't help me figure out the plot points, at least I had a grasp of the characters. As with any of these kinds of books, the review has to be very vague so as not to spoil the narrative. I will say that the writing was highly engaging, flowed seamlessly (hard to believe that it was co-written), and addictive page turning prose. While the final twist was totally unexpected, I'm not sure that it was even necessary to propel this as a first rate thriller.
Another addictive, page turning thriller that will have you flipping pages to figure out what makes these characters tick, and who is the real villain. A perfect book to devour in short order, you won't want to put this one down.
