Time Shelter is the first book written in Bulgarian to be awarded this prize. In the book, “clinic for the past” proposes a viable therapy for Alzheimer’s patients: each level meticulously recreates a decade, sending patients back in time. But eventually, the past starts encroaching on the present.

Lela Slimani, a prize-winning French-Moroccan novelist, was the chair of the International Booker Prize 2023 judging panel. On May 23, she announced the winning book at a ceremony in London’s Sky Garden. The panel also comprises Tan Twan Eng, a Malaysian novelist who was shortlisted for the Booker Prize; Uilleam Blacker, a leading literary translator from Ukrainian to Britain; Parul Sehgal, a staff writer and critic at the New Yorker, and Frederick Studemann, the Literary Editor of the Financial Times.

The greatest piece of foreign fiction that had been translated into English was sought after by the 2023 judges, who looked for submissions that had been released in the UK or Ireland between May 1, 2022, and April 30, 2023.
