A different world, she said. That is also our world. That’s the bit that’s complicated.

My first guess was that it was the ‘different’ that’s like in those alternative-history stories. You know, the Nazis won the Battle of Britain and took over the country. That kind of thing.

But that kind of different wouldn’t give us Uncle George and Aunt Kat. Or the house.

It’s a different kind of different to that.

Kind of hard to describe that different, though. Even with everything I’ve read so far in her papers.

This one’s hard.
