What's worse than reading a mediocre book? Reading a mediocre book and half way through realising that I've read it before. What is even worse than that? To continue reading, because I could not remember how it ends. That's how memorable it was. I am a sucker for books about books, secrets and mysterious powers that can be drawn through the art of reading. But this... the central concept is thin and stretched, the characters and the collisions of their interests predictable, the story arch fits the cheap thriller genre so there are no surprises whatsoever if you know the general rules of the game. From the obligatory final confrontation the plot follows a quick and happy line to the end without the slightest twist. The writing is very average. I am posting this review mainly so I remember not to pick this book by mistake for the third time!
