The abolition of species

"The world as we know it is over. Man's reign on earth has come to an end, and the reign of the animals has begun. The indifferently wise Cyrus Golden the Lion rules the three-city state that is now what remains of Europe. Yet, other forces stir while the king of beasts sleeps--the last struggling human resistance, the Atlanteans with their mysterious undersea plans; the factions of Badger, Fox and Lynx within the empire itself; and, in the jungles across the ocean, a ceramic form of postbiological life. Cyrus the Lion sends the wolf Dmitri Stepanovich on a diplomatic mission, and in the course of his journey he discovers truths about natural history, war, and politics for which he was unprepared."--Goodreads.
