I expected to have real explanations of the actual creation of the labyrinth, and in fact, we learn other things ... and we discover new characters. I always like to read this author! his way of writing that does not want to stop ;-) However, I found this tome a little worse than the first three that I had eaten! a rather long game for my taste (fights to repeat), and once or twice fetched ^^ otherwise I finished after putting his nose in it three times, so a good book, in short! ;-)
