Goodreads asked Alan Denham:

Where did you get the idea for your most recent book?

Alan Denham You mean the last one published, or the one I am still working on? In the first case, it needed several ideas - 'Magic' is a collection of related short stories. Some of the ideas were mine, some were Graham's. Some of them are quite old (ideas Graham and I first played with many years ago), some were new(ish). They mostly integrated fairly well.
If you meant the book I am still working on - one of the shorts from 'Shades of Magic' was too good to leave - that short is (hopefully) becoming the first chapter in the next book.
