What if you created your own conspiracy theory - and suddenly, everyone believed in it?

What happens when a party gets so out of hand that some hungover students come up with a crazy idea? On a whim, Benny and his friends invent a harebrained story about the visit of aliens. They make up a secret symbol that they spray all over town and post them under fake social media accounts. Benny, Nando, Till, Darya and Liv are mostly curious to see what will happen and if people will believe their conspiracy theory - Liv is also excited to have a topic for her bachelor's thesis in psychology. But to their own surprise, more and more people believe in the story, especially when an anonymous user called "Octavio" starts dropping mysterious hints. Benny’s attempt to clear everything up soon puts his life in danger.

Bestselling author (#1 for German YA) Ursula Poznanski's new thriller is a vigilant analysis of the mechanisms of modern superstition and a shocking thriller about a prank that becomes confusing reality.
