Goodreads asked T.W. Iain:

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

T.W. Iain That's tricky. I find ideas come from all over the place. Usually, by the time the book's written, the original idea has morphed so much that it's hard to recall its origins.
My most recent book is Expedient, which is a side-story novella that came about while I was writing Deep Water (Dominions III). That book had some stuff about 'body pouches', and I started wondering if it would be possible to have a removable section of skull in which to store items. I'd seen a documentary some years ago about a woman who had a huge hole in the middle of her skull, where her brain should have been, and yet she still functioned normally, so I thought that a small 'pouch' wasn't too unrealistic.
I let that idea simmer, and it developed into the story that became Expedient. So the idea came from a 'what if' combined with something I'd seen years ago.
