Tatiana de Rosnay writes historical and contemporary fiction about family secrets and the way past events remain hidden inside ordinary homes and relationships. Sarah's Key alternates between Paris in 1942, where a Jewish girl is caught in the Vel' d'Hiv roundup, and a present-day journalist investigating the history of the apartment connected to Sarah's family. The House I Loved is set during Haussmann's reconstruction of Paris and follows an older woman resisting the demolition of her home, while other novels return to memory, inherited secrets and French settings. De Rosnay's prose is accessible and character-led, with historical research usually tied to a personal discovery rather than presented separately. Sarah's Key is the clearest route into de Rosnay's dual-timeline historical fiction, while The House I Loved focuses more narrowly on memory, place and a home threatened by urban change.
