Yes, for anyone who is interested, the Scrivener project file (available on the book’s library page) contains all the chapter briefs that everyone received, and some Scapple maps used to plan the book out. The compile setting used are also available for download on the same page.
Big thanks to everyone who took part. We had three people not submit in the end which caused the slightly late posting of the completed books (although all 9 versions were actually finished and on my desktop by 23:57, it just took a bit of time to upload them and write the pages with the right links!), but HUGE THANKS to Keith, Ioa and the whole team at LL for generously hosting the event for the past 8 years, and for making Scrivener and Scapple, without which attempting this kind of event would be inconceivable!
