SF essential book! Beautiful writing, sometimes raw, which allows you to fully immerse in the universe created by Pierre Planking. Endearing characters, everything separates between the East and the West ... We are here on earth, and humanity is divided in two by a large electromagnetic wall for over 2 centuries. Why? The author explains very well the mechanics that led to it based on many historical reminders of previous wars. Some who really existed (the first World War, 2nd ...) then those leading up to the book situation. A part of the world where everyone lives without problem until more than 100 years while the other lives in utter misery ... Read on! And fast!
