Love and Romanpunk - Tansy Rayner Roberts
The story, "The Patrician" won the 2012 Washington SF Association Small Press Award. It also won a Ditmar Award.
Thousands of years ago, Julia Agrippina wrote the true history of her family, the Caesars. The document was lost, or destroyed, almost immediately.
(It included more monsters than you might think.)
Hundreds of years ago, Fanny and Mary ran away from London with a debauched poet and his sister.
(If it was the poet you are thinking of, the story would have ended far more happily, and with fewer people having their throats bitten out.)
Sometime in the near future, a community will live in a replica Roman city built in the Australian bush. Its a sight to behold.
(Shame about the manticores.)
Further in the future, the last man who guards the secret history of the world will discover that the past has a way of coming around to bite you.
(He didn't even know she had a thing for pointy teeth.)
The world is in greater danger than you ever suspected. Women named Julia are stronger than they appear. Don't let your little brother make out with silver-eyed blondes. Immortal heroes really don't fancy teenage girls. When love dies, there's still opera. Family is everything. Monsters are everywhere. Yes, you do have to wear the damned toga.
History is not what you think it is.LOVE AND ROMANPUNK.
