Wikipedia said:This science fiction duology tells about a distant future in which the "German nation" became the human hegemon in the Galaxy, namely through abandonning its Nazi ideology in favour of a multicultural "Empire Above All" nationalism. The book centers on the quest of Ruslan Fateev to attain independence for his homeworld of New Crimea, the sole Russian-speaking corner of the Empire (according to the books, the overwhelming majority of Russians chose voluntary germanisation over the centuries). All this is set in an atmosphere of uprisings of a federation of colony worlds against the Empire and the invasion of human planets by mysterious alien creatures named "Biomorphs"
It's like my personal dystopia made manifest. Seriously, you Russians have a knack for unending horror.
