I know what you are thinking

As St.Jorge day is arriving, I've decided to write about books. Right now I've got plenty of them still waiting in my bedroom to be read because during school days I don't have much time to read and I'm still finishing one. Anyway, I've always liked going to bookshops and see what kind of new books arrive and which attract me. So I did so and I saw a new book from John Verdon, called "I know what you are thinking". I guess that like most of people, it attracted me firstly by the tittle and then, by the picture on the front page(which you can see in the photo). I didn't know any book by John Verdon and I think I only heard once from that book, but I didn't paid much attention. So I started reading the backpage and it really catch my attention. It's about a man who receives a little envelope which contains a letter. It suggests him to think of one number from 1 until 1000 and, when he does so, he opens the envelope and discovers that the number he thought is the one which was already written in the letter. After that, this man starts investigating with a policeman about who could be the author of the letter, but what at first seems a game and a joke, it ends being a criminal who knows what his victim is thinking.
Does it sound well to you? I like books which capture me from the first page so perhaps I'll buy it. But on the other hand, I get scared very easily so I don't know if I will be able to finish it. I will have to find out! I'll let you know it if I finally read it ;)

PS: "I know what you are thinking" it's the translation for "Sé el que estas pensant", in Catalan, but I think in English this book is called: "Think of a number".
