When a video depicting the brutal murder of a former classmate leaks online, Kylie Bennington’s curiosity gets the better of her, leading to the discovery of an off-the-grid social media app called MonoLife. As it turns out, there are certain cryptic rules in the user agreement that must be adhered to, such as interacting with other users at least twice daily or risk losing it all...and never, ever speaking of MonoLife’s existence to non-users or risk dire consequences. For this is a platform that primarily rewards the worst in human behavior and which begins chipping away at Kylie’s sanity across post after post for an ever-increasing audience of immoral fans. Now Kylie’s going to find out just how far she’s willing to go on her unyielding rise to the top --- even if that means coming face-to-face with the frightening and ruthless forces behind MonoLife, who see all from deep within the shadows.
