Sybille Ruge’s ice-cold antiheroine Sonja Slanski is equally at home in the shady milieus for the financial capital of Europe as she is in the glittering upper echelons of Frankfurt high society. But when Slanski's half-sister Luna, an “escort artist”, is found dead from a seeming overdose in the protagonist's apartment, Sonja has to fight her way through a jungle of powerful interests that gets more menacing with every new discovery. But Slanski is a boxer, and is always ready to fight to the bitter end once she’s taken on a task. Sibylle Ruge’s unconventional “female noir” debut landed on the thriller bestseller lists as soon as it was released in 2022. Now, the film rights have been secured for an English-language adaptation, taking this story to an international audience.
