Kim de l'Horizon (born Dominik Holzer; 9 May 1992) is a Swiss nonbinary[4] novelist, playwright and thespian.

[1][21] In 2022 De l'Horizon was completing a master's degree in transdisciplinary studies at the Zurich University of the Arts.

[9][18] In the novel, the non-binary narrator resides in Zürich, after having escaped from life in a small conservative village in Switzerland.

[21][6][5][11] The jury for the German Book Prize based their decision on the "urgency and literary innovative power" of de l'Horizon's novel, which they were "provoked and enthusiastic" about.

[32] Sabine Kieselbach of Deutsche Welle stated that this sort of reception had never happened before in the history of the German Book Prize.

[37][38][39] People gave Blutbuch one-star reviews on Amazon, and security was provided for de l'Horizon's appearances at the Frankfurt Book Fair.
