Jens Forwick is your classic book rat. Free time? Next book. If you do that for over 30 years, some of it's gotta stick.
The author began to write and play (but mostly play) games in his early youth. He did some short stories, some scientific stuff, even some scifi saga on a galactic scale, just for himself. A few years ago, he discovered Litrpg. He read everything he could lay his hands on, and then he thought: "I can do this."
So he did. And now you can read it.
