De zwerm

A German-language television series adaptation of Frank Schätzing's novel, titled 'The Swarm,' was produced and released in 2023. It features an international cast and expands on the book's narrative.

Frank Schätzing has stated that 'De zwerm' is a standalone novel and he does not plan to write a direct sequel. The story reaches a conclusive ending within this single volume.
