We often hear theories about parallel worlds in which history unfolds along several different scenarios. One such world is where our contemporary, Major of the Medical Service Igor Ivanov, ends up. He arrives there dying in our world, after being blown up on a mine. A world war is underway, and Russia has it rough. In the second book, the hero gains a new body. Now he is a nobleman, Dovnar-Podlyaisky, but the surgeon’s skill and the officer’s honor remain with him as before. He continues to treat people and save the Fatherland.
