From the author:

Wisherton was sort of my daughter's idea. I think it was about three years ago that she asked me if we could write a book together. She'd have been about eight years old. We sat down with a notebook and filled a few pages with ideas. I wrote a sample chapter and gave it to her to read. I figured she'd mark a few things and have thoughts about where the story should go next. She returned my pages with nearly everything crossed out. I think there were two sentences that she liked.

Clearly, writing together was not going to work.

I shelved the project indefinitely. Meanwhile, another child kept asking me when I was going to write someone else like Zero Station. I really didn't want to go back to sci-fi so I kept thinking about that Wisherton fantasy. I thought he'd like it if I could figure out how to write it. What I eventually came up with bears little resemblance to the story my daughter and I originally brainstormed.  Except the place name, I stuck with the name she chose. And while she didn't end up writing this book with me, she did help me draw the map on the cover.
