The best books unfold like movies for the mind, with readers compelled to visualize the events in living color, as they unfold in black and white on the page. The horror debut novel Bird Box is a conundrum: a novel that directs readers to visualize being unable to visualize anything. Set partially in a post-apocalyptic future where just looking around at the world could be fatal, it puts readers in the place of characters who have to operate blind in a world full of threats—including some malign new ones. It’s fundamentally impossible for the protagonists to know exactly what’s menacing them and why, and first-time author (and The High Strung frontman) Josh Malerman suggests that this uncertainty, and the constant temptation to counter it, might be the most frightening thing of all.
