Here is a short story my daughter and I wrote shortly after I found out about the Choosatron. It was the first attempt I'd done at a Choose Your Own Adventure style of writing in quite some time, and is designed to be a children's story for younger girls.
You should be able to import it into Choosatron Write. Be aware that Choosatron Write will be very slow once the story has been imported. It needs a lot of work to be fully optimised.
I had to import the story manually, and I may have messed up some of the links to some parts of the story. Please let me know if options don't point to the correct passage.
Extract the .json file from the story to a directory on your hard drive, then click Import Story -> Import from JSON. It takes a minute to import.
