Nicola Griffith is best known for her science fiction novels (Slow River, Ammonite), but she switches gears in her excellent new novel, Hild. It's set in 8th century England and is the life story of a girl named Hild who would go on to become St. Hilda. We caught up with Griffith at BookExpo America 2013 and talked about her inspiration for the novel, how writing it was different than writing science fiction, and which classic writer she just can't stand.
