Famous Men Who Never Lived

This was a terrific, if occasionally confusing, story about a world in which... the reality timeline splits into two sometime around 1909 and there are (at least) two existing earth. Something happens to one of them and it becomes doomed, someone develops a mechanism to transport a few hundred thousand people from the dying world into the other. This is how a few of them find meaning in their lives. I didn’t like the protagonist and I don’t think you’re supposed to. Everyone’s a little broken and part of this is thinking about the trauma of leaving not just your family or your friends but your TIMELINE and having to learn to live in another one,similar yet slightly different with 100-ish years of difference. Thinky but not TOO thinky.
