“I’m alive... again?”Adam died and was brought into a fantasy world. Then he died again, and has been reborn into a new (?) fantasy world. His life, as before, is in the hands of the dice. Come and join Adam as he rolls his way in and out of trouble. The story has a very slow pace, and has elements of really light hearted, wholesome stuff, and really dark, gruesome stuff. Sequel/Reboot of Beyond Average. You don't need to read Beyond Average, but it will explain a lot about Adam.Also, you can start at the beginning of each year (301, 501, 701, 901, 1001, etc), because most of the systems and relationships will be partly explained when they come up, and most others are easy to pick up after a few interactions. Finally, I am also currently in the middle of editing and rewriting the first year, and perhaps other years. A lot of my early chapters are a rough read, and even I cringe reading them.
