Canadian actor Keanu Reeves will publish his first novel this year in collaboration with British author China Miéville.

Their joint novel is titled The Book of Elsewhere and is set in the world of the BRZRKR comic book series created by Reeves, first published in 2021. It follows an immortal warrior on a millennia-long journey to understand his immortality.

The novel is due to be published on 23 July by Penguin. Reeves, who is best known for his roles in The Matrix and John Wick franchises, said it was “extraordinary” to work with Miéville. “China did exactly what I was hoping for – he came in with a clear architecture for the story and how he wanted to play with the world of BRZRKR, a world that I love so much. I was thrilled with his vision and feel honoured to be a part of this collaborative process.”

Miéville’s novels include The City & The City, Embassytown and Perdido Street Station. He is the only writer to have won the Arthur C Clarke award for science fiction three times.
