I pride myself in being able to research any historical period, using any type of resource. No sitting at home checking Wikipedia for this writer. I hie me to a university library and dig in for the day, then go back for more.
But here's what I'm finding I can't do: I can't think in terms of adult historical fiction. What's that about, do you suppose? I'm staggering under the weight of all the original middle-grade historicals I'm dreaming up. I'll never live to write them all. But when I try to sprout a story idea for adults, all I can think of are things I know already exist.
I'm about to take a short vacation. I'm determined that one of my travel projects will be to come up with a historical fiction plot of interest to adults. It needn't be about where I'm visiting, but getting away from home will surely jump-start my imagination.
