I just read this book that I totally sucked into his world of the first letter to the last point. But what book is this taking so must you ask yourself you behind your screen? So let me explain. From the first sentence it is already immersed in the plot, no fuss, no detours, it was indeed aware that there is more to discover after this first sentence. It is so well done that barely a paragraph I am surprised to have me ask a dozen questions, to speculate at all costs, trying to solve the puzzle before even knowing the statement. Eager for answers so I continued my reading word by word with ever greater determination to understand what was happening, to discover the word end of this very mysterious history. But I was not at my sentences since the answers to the questions we ask are given sparingly, with not too little information, or not enough. That's the magic of Kraft, everything is finely proportioned, available in time to drive and hour, just enough to push it further in reading and let him construct new theories. The book is structured as chapters sometimes directed at the past sometimes on the present. In some books it is unbearable and we just want it to skip some chapters to trace the course of the current chapter. Not with Kraft, we take whatever we give Matthew stride, it asks the same so it's good. In fact, each chapter has a beginning and an end so well done that we can move from past to present and vice versa without staying on end. Everything revolves wonderful, not a single false note in the wheels, this alone file and finally the 107 small pages of this book are almost too fast read. I will of course not you spoiler in any way, it would be incorrect to thee future reader (?) And towards Matthew who spent time to set up this plot, but I will still tell you in addition to its captivating writing this book is worth reading for its denouement that was for me a true slap. I have concocted theories, some good, some far-fetched, but then that? I have never thought there. In short, all that to say that this book was a pleasure to read and that Matthew is now one of the authors I'll follow, I want to know a little more of his world, find out what else has to offer us . Besides, I lead it not procure his other work: A day in advance. With that, do not disturb, I read.
