Be aware that by opening this book you will inevitably take a very strange passage, like this limping narrator who makes his entrance here and there, a journey through a kind of interdimensional door linking this whole series of stinging, sometimes disturbing stories, linking singular eras or particular little universes, unless it is simply a matter of dreams… I leave you to discover, or even guess, the exact nature of this indispensable wormhole which could cause you some uncontrollable discomfort or emotion.
