Hi and not to worry, your English is about a hundred times better than my Russian.
The only Brass/Sara fics I know of are on fanfiction.net. Some really good ones are by Emihn (Mirrors), Geeklovefan (A Departure from the Norm), loose-cannon-with-a-gun (Dreams) and Pseud0me (What did you say). Both Mirrors and What Did You Say are WIP's but they are still very good. If you read German, loose-cannon-with-a-gun has several excellent Brass/Sara stories. There are also many Brass/Sara stories by Judge-Douglas-Mason.
