Book of Iron is out tomorrow! (Some early orderers seem to have copies already.)
This novella is a prequel to Bone and Jewel Creatures, although it stands alone. It's set in the same world as the Eternal Sky books, and it features roadsters, necromancy, and miserably complicated interpersonal relationships. Like you do.
Also, pre-orders are now open for the shared-world audio anthology METAtropolis 3: Green Space, which features Jay Lake, Ken Scholes, Karl Schroeder, Tobias Buckell, Seanan McGuire, Mary Robinette Kowal, and me! It contains my seasteading caper story "Green and Dying" along with novelettes and novellas linked in time, place, and setting, written by the rest of the gang.
It'll be released on October 15, and it's going to be awesome.
