Quick Heroes rec
One of Us is an inspired Heroes AU modelled on the show Carnivale. Which you don't need to have watched in order to understand this story, but if you have, it adds a little frisson. No spoilers for Carnivale, spoilers for Heroes only in as much as who has which superpowers is concerned. Go and read about Mr. Linderman's Magical, Wonderful Traveling Show as quick as you can!
