If we disregard the author's personality in a high propensity to consider the protagonists of his adventures outside his circle as perfect idiots (which they seem to be at times, but the narration deserved more subtlety ...) the subject matter is quite unusual and well treated. Easy playback does not diminish the interest of the text, and we get caught up in the twists of the story sometimes on the verge of the grotesque when through the administration are pointed. After reading, those who never did wear a fresh look at the urban jungle and will question the hidden parts of Paris that the eyes of quidam never see. For this book is the story of those who exploit voluntary hiding to invest places abandoned by our daily lives and been forgotten, or simply prohibited.
This book is proof that our cities are full of places that deserve to be held on the margins of our usual concerns to retain their charm and appeal, and inflame our taste for transgression. As for those who dare to cross those limits, they will benefit (and will benefit others) of these ground incursions prohibited.
