Last month, author Arthur Slade talked about steampunk at Cynsations.
I recently gave my niece Airborn with a note saying that it was an example of steampunk. So I've been concerned that she might ask me what it is. I like Slade's definition--"it’s science fiction inspired by the aesthetics and atmosphere of the Victorian era." Now I just have to rework "aesthetics" and maybe even "Victorian era" for a twelve-year-old.
