Tuesday, July 15 Nicola Griffith is a publisher's dream. Her science-fiction novels include Ammonite, a femme-centric tale of a world with no men; and Slow River, an award-winning cyberpunk adventure centered on lesbian characters. She's edited three Bending the Landscape anthologies, in which gay authors showcase horror, fantasy and sci-fi stories with queer touches. Finally, her mysteries starring the no-nonsense, Scandinavian, lesbian sleuth Aud Torvingen are acclaimed for their sensuality and journeys into self-discovery. So Griffith is a triple-dipper -- sci fi/horror, mystery and gay readers all want to crack open her books. Her latest, Stay, finds detective Torvingen searching for a sociopath. Meet Griffith and ogle her Joan-of-Arc-style hairdo at Left Bank Books, at a free 7 p.m. reading and book signing. Call 314-367-6731 for more info.
