Star Wars Infinities by Adam Gallardo
This is a great series for anyone who has ever wondered "what if that scene had turned out differently". Each Infinities book approaches one of the original trilogy and changes a single event, one encounter that ends differently and changes the entire trajectory of the story leading to some surprising results. While the art is mediocre, the plots are fascinating. I've actually only read 3 of the 4 parts of the Return of the Jedi story but if all the rest are anything like what I've read these are well worth a look.
