It's small. It's quiet. It sees everything. Jonah is seventeen and well ahead of his peers in intelligence and comprehension. However, he is also very talented at making himself unpopular with others and at getting infected. Jona reacts to the rejection in its own way: He lets his private research object loose on his envyers: a drone. Small, quiet, equipped with an excellent camera and able to track down any person whose mobile phone number Jona has. With what he sees in this way, he can defend himself against mockery and malice. But then he learns something that would have been better left undiscovered, and suddenly he is in mortal danger. Drones, surveillance, manipulation, dark secrets - Ursula Poznanski skillfully weaves highly topical themes into her new thriller. The mirror-Bes.
