September involved some travel and other transitions for me, so I spent almost all of it reading a single series.
The Desert Storm by Blue_Sunshine and its sequel series are well over a million words of Star Wars time travel AU: when Luke and Leia are small, Ben Kenobi is caught in a sandstorm on Tatooine and ends up in his own past, when Anakin Skywalker is only three or four. Ben takes Anakin and his mother Shmi to the Jedi Temple on Coruscant, not revealing his identity because his younger self is around, and starts trying to make changes to save the Jedi Order and the galaxy from the Sith. There’re a bajillion characters from the various Star Wars cartoons as well as the prequel movies, and some original characters, and of course each change causes more changes. I very much enjoyed all the elements about Jedi culture, Mandalorian culture, and Alderaan, without knowing what was canonical and what was original. The story gets indulgent at times (appropriate for fanfiction!), and needs serious proofreading, especially for certain homonyms, but that didn’t stop me from reading this epic. And reading it. And reading it. The series goes on to a second series, focusing on the alternate version of Obi-Wan Kenobi, which is still in progress.
