Alphabet Squadron is a Star Wars story set in the times after the Return of the Jedi movie, when the Empire is divided, and the New Republic (the Rebels from the original Star Wars trilogy) is beginning to gain power.
Those who were part of the Imperial military attempt to make a violent display of the strength that they still have, attacking a number of worlds, destroying civilizations in the name of preventing the New Republic from using the resources from those planets. During one of these raids, a highly-skilled TIE-fighter pilot comes to the realization that this Empire that she had been committed to is not the force of Good that she had previously believed. She defects from her squadron, getting shot down in the process, and is captured by people in New Republic Intelligence. Over the course of the story, she is thrown together with several other misfit pilots, trying to ultimately stop the Imperial squadron of which she was originally a part. Overall, it's a fun and quick read, that will be a fun addition to the greater Star Wars story.
