When Cath receives her invitation to The Event—a monetised retreat for social media influencers—she can't believe her luck. Irene Jobert is the most famous influencer in the world, and now Cath will be one of the five participants chosen to stay with Irene in a renovated Transylvanian monastery. The catch? Their every move will be live-streamed to millions of people around the world. Patrons pay for constant access to their favourite social media stars: Irene, the model; Nathan, the gamer; Jules, the blogger; Daniel, the fitness guru; and Cath, the writer. Nestled halfway up a mountain, the five are isolated, with nothing but the internet to connect them to the world. That is,until eagle-eyed live-stream followers all around the globe notice a sixth participant. A dark figure lurking in the background. They thought they were alone. Perhaps they were wrong.
