The main characters of the novel “Reverse of Life, or Confession of a Billionaire” are completely different people, occupying social positions that are incomparably distant from each other. Nikolai Gudimov is an adventurer, a man of war, capable of engaging in battle with a numerically superior enemy. Alexander Kriegert is a law-abiding citizen , a talented entrepreneur who managed to create a gigantic industrial empire. But they have one thing in common: a willingness to come to the aid of those who find themselves in great trouble.
