Yes, I know it's November, but May is the theme of this short story competition that you may wish to enter (see what I did there?) You may not want to bother reading all the t&cs but I think you should. There's a bit about copyright that I think might just refer to the winner. I'm trying to find out.
The prize is a week's holiday in a Duchy of Cornwall manor house which sleeps up to eight. Make a good writing retreat, wouldn't it?
Here's a picture taken in my garden this May. It may, or may not, inspire you.
