Hi. This isn't a good solution, but you might try this. Search for Montgomery as author. I think you want R.A. Montgomery but I'm not positive. From there, all of those are choose your own adventures. Select the user Eric Troup on the download page. That will give you a list of everything he submitted. He submitted them in the first place. They will have numbers in the title to indicate where they are in the series. This is at least a start.
