Really my Idea just stemmed mostly out of thin air and a love for comic books. Although I do recall getting some motivation from Fallout 3.
I know that might sound a little vague honestly though I can't say my motivation for this story came from a book. The Mammoth book of Steampunk sort of helped me get to know the world of Steampunk so I guess if any book motivated my story it's that one.
For me it is not really one particular book that has inspired my story. All the good books I have read have inspired my writing somewhat and the story I am writing is in the style I have crafted from all my different sources of inspiration.
