Nothing to do with what I expected. The book begins very well, black humor, originality, cynicism, a good thriller in perspective, until the imagination of the author overflows and takes us to a fantasy thriller which I have not hooked at all. Cartesian Not enough for my taste, and as the end towards a second volume, I'll never know the result because I do not read. And all that is advertised to sell the book is not necessarily fair, hence the disappointment perhaps.
