Sin Blaché

Sin Blaché is an American author based in California, known for co-writing the 2023 novel Prophet with English author and naturalist Helen Macdonald, marking Blaché's debut as a novelist. Described in reviews as a high-octane science fiction thriller, Prophet paired Blaché's genre sensibility with Macdonald's established literary reputation, drawing attention as an unusual creative pairing between an emerging genre writer and a mainstream literary author best known for nonfiction. The novel introduced Blaché to speculative fiction readers as part of a two-author collaboration, making Prophet - Blaché's sole published novel to date - a distinctive entry point into contemporary science fiction thriller writing.
