The end of humanity might be nigh. People are turning into automaton “sleepwalkers” drawn by a need to walk the highways toward some mysterious destination. They’re still human, but they no longer need food or sleep. How does the rest of the world respond? Fans of apocalyptic fiction have rated this book highly on Goodreads, but this is not a bright light of the genre. The writing is breezy and colloquial and the demands on the reader are few, but it feels as if we’ve met these characters before, in many different books. Despite the novel’s length (800 pages), there’s not enough there there. Reviewed on Oct. 22, 2020
