Adam asked James Alan Gardner:

So when can we expect the next Spark novel?

James Alan Gardner I'm afraid the publisher didn't renew the contract on the Spark novels. (Sigh...) I have the next book plotted out -- it's centered on Miranda -- but I've had to set it aside and work on something else.

So my new book is very close to being finished; I describe it as "Sailor Moon meets Doc Savage in the French Revolution". But who knows if any publisher will buy it? (Before you ask, if it doesn't sell, I'll definitely consider self-publishing.)
