The book of elsewhere : a novel / Keanu Reeves, China Mieville.

A mind-blowing epic from Keanu Reeves and China Mieville, unlike anything these two genre-bending pioneers have created before, inspired by the world of the BRZRKR comic books. She said, We needed a tool. So I asked the gods. There have always been whispers. Legends. The warrior who cannot be killed. Who's seen a thousand civilizations rise and fall. He has had many names: Unute, Child of Lightning, Death himself. These days, he's known simply as "B." And he wants to be able to die. In the present day, a U.S. black-ops group has promised him they can help with that. And all he needs to do is help them in return. But when an all-too-mortal soldier comes back to life, the impossible event ultimately points toward a force even more mysterious than B himself. One at least as strong. And one with a plan all its own.
