I'm Beth Daniels, the author of GEARED UP WRITING STEAMPUNK, a book that is now in it's 3rd update. Still seems to be the only volume out there that specifically targets the elements that go into writing Steampunk.
I actually write Steampunk, Dieselpunk, and Gaslamp Fantasy as Nied Darnell, so there are lots of versions of alternative history that I love spinning.
I'm here for the Tea in the Clouds convention to answer any questions you care to fling at me. In doing the many online workshops I presented regarding Steampunk, I deconstructed a lot of classic Steampunk tales. While I tend to write more Weird West personally, I love the Victorian settings, too. Having a BA in American History and British Modern History (which is actually Elizabeth I to Elizabeth II), I saturated myself in the 19th century on either side of the Pond.
So, welcome to the Convention, and toss those questions!
