Dead Astronaut by Jeff Vandermeer

Grayson, Moss, and Chen are astronauts turned rebels, navigating version upon version of a nameless City created by the villainous, all-powerful Company, familiar to readers as part of the Borne universe. The City is overrun with the results of the Company’s ill-considered experiments. This is a world where a blue fox is an echo across space and time, prophetic. Where a fight in which the duck may or may not be on your side. A leviathan waits, as do other versions of yourself, and a mysterious former comrade known as Charlie X. This is not just one world, but many...and can these worlds be saved? 

With Dead Astronauts, Jeff VanderMeer continues to expand and explore the mind-bending world of Borne at the top of his game. Demons, madmen, monsters, and endless twisted wonders await readers brave enough to take this miraculous dark journey.
