And I thought "future fiction" was the books I hadn't yet written.
So, we're into sub-sub sub-categories, are we? How about a letter for any book which contains a character or event which is historically correct combined with elements that are fictional? Or one where some non-human species (biological, magical, spiritual or electronic) is capable of comprehensible communication? Give me an hour or two and I can get as many letters printed on the spine of the book (with recommended reading age, and the time and location atwhich it is most likely to be appreciated( as the author has managed to get onto the pages.
And if, despite having described some gadgets accurately enough that they now exist, science fiction has been slightly less accurate in predicting social trends, I still like to think that "Brave new world,"A jagged orbit" or "Level seven" have done a tiny little bit to warn people, to prevent the state they describe ever coming to be.
Still. I might just be an optimist.
