Just read the excellent Abernathy Trilogy by Kristen (Kristin?). Her other works are Glory and Three Days. Both are linked here at getithere. There is one other story mentioned 'Rome' and I can't find it. Does anyone know where to look or got a download link?
Much appreciated!
Edit: Seems there is no fic with the name 'Rome'. Kristen's fic 'Glory' is set in ancient Greek. One story with a Roman background is 'Edge of the World' by crazyundeadfairy
