Aron is an odd young man who loves bees and beekeeping. When he was a child his father died in a brutal and strange way before his eyes. Since then, he has had a feeling that he should retaliate. But on whom?

Aron follows his instinct which takes him far from home but closer to his origin. The dramatic stories of a foolish experiment, an imprisoned cage girl and evil forces roll up.

The half siblings Nelly and Jonas were victims of abuse as children. The experiments that were performed on them equipped them with extreme intuition and an increasingly symbiotic friendship. Now they have decided to do something positive of their fate. But the remarkable power is unpredictable. Sometimes it puts a spoke in the wheel.

The financial genius Nelly suffers from melancholia ever since her daughter Lilja was born. She feels trapped and confined. And it will get even worse. Jonas works as an analyst at the enigmatic security firm Apisec. He faces an approaching kidnapping wave of small children. He also has a hard time trying to approach his colleague Isabella.

What do Nelly and Jonas have in common with Aron? The connections reach far back in time, to one of science’s darkest chapters. One fatal mistake that set mankind’s life conditions at stake.

The Cage Girl is a standalone sequel to The Butterfly Boy and an elevated thriller about love, friendship and ruthless anger. And about the bees, the vital but endangered small animals that make sure the plants we eat are pollinated.
