Faber writes literary fiction across multiple genres, from Victorian-set historical narratives to speculative science fiction. The Crimson Petal and the White, his most prominent work, combines intimate character study with meticulous period detail, following a prostitute navigating Victorian society and the men who desire her. Under the Skin ventures into darker territory with its alien narrator observing human vulnerability. His fiction typically explores moral complexity and psychological depth, examining desire, connection, mortality, and what it means to be human. Readers drawn to character-driven narratives with philosophical undercurrents and willingness to inhabit uncomfortable perspectives will find compelling work here.
