I feel SF is going through an experimental phase right now.
I describe my plots as follows; A character is walking down the street when all of a sudden a piano falls on them. They spend the rest of the story digging out from under that piano. How they dig, how long and how well, this all depends entirely on the character.
First and foremost, The Quiet Invasion is a first contact story. What would we do if we actually found evidence of alien life out there? It's also about politics.
Fantasy is, of course, booming, and I think it's beginning to stretch its range as well.
Becoming a mother cannot help but change things. An author's life is reflected in their writing, whether they want it to be or not, and parenthood is one of the biggest life changes there is.
All of this got me thinking about the history of the westward expansion, and got me to wondering how the exploration of the Solar System would be changed if there were an indigenous presence out there.
Actually, after while, finding the ideas is the easy part. Sorting them through and turning them into stories, now, that's the hard work.
I suppose if I was to have to pick a few, Ursula LeGuin would have to top the list. It was while reading her work that I decided I wanted to be an author.
Fortunately, many people also enjoy a stand-alone as a sample of something new, like trying the special at a favourite restaurant one night instead of going for the usual.
