I have a publication date for The Grass King's Concubine -- 7th August 2012, just in time for Worldcon. It's available for pre-order from various places. I am so excited: I've lived with this book for almost as long as Living With Ghosts: I began the earliest version of it back in 1995, although it's changed a lot since then. I love the characters and the setting. It's in the same world as LWG, but in a different place and set about 150 years later. And while LWG focuses on a city, GKC is set mostly in the world of ghosts and spirits -- the variundarii that Gracielis talks about. It has a stubborn heroine, a patient hero, a set of other-worldly warrior-guards and shape-shifting ferret twins. I'll keep you posted about promotional events, cover details and so on.
