Gird your loins, Prime Minister. Charlie Brooker is bringing his mind-warping TV series to bookstores in early 2018. Brooker is editing a book version of Black Mirror (the first in a promised series) "featuring original stories from leading fiction writers, all set in the world of the cult series".
Smart move and after all, Brooker was influenced by Roald Dahl's Tales of the Unexpected (which appeared first in book form).
