I liked this one! Yet another great Pratt story, yet more reason why he's one of my favorite authors (I've got an interview with him coming up in Fantasy Magazine, woohoo!).
This was an example of a good title. At first it seemed straightforward, the origin story of his brother, but it became his own origin story and I liked that twist. The idea that he can't die because he isn't supposed to exist is an interesting one, all the more support for the universe being a glitchy computer program.
