Failure.
The REBEL ALLIANCE is on the verge of defeat. Following a daring mission to the Imperial research facility on Scarif, ROGUE ONE managed to capture the plans to the EMPIRE's new and powerful superweapon: the DEATH STAR. Putting the lives of the entire galaxy on the line, BAIL ORGANA entrusted the delivery of those plans to his daughter, Princess LEIA ORGANA.
However, the EMPEROR's apprentice, DARTH VADER, tracked the Princess and her ship, apprehending the rebels and confiscating the stolen plans aboard the TANTIVE IV. With the plans and the Princess in his possession, Darth Vader returned to the Death Star to destroy the Alliance's HOPE once and for all.
The fate of the galaxy and the balance of the FORCE are irrevocably changed as the Princess of Alderaan learns the true nature of the DARK SIDE....
(This story is a complete reworking of the entire Original Trilogy. I'm going to be borrowing material from both canon and legends because of it, but everything prior to A New Hope, including Rogue One and the Clone Wars, is all taken as true.
This will be the first book in a trilogy I'm hoping to make, so stay tuned or leave some comments if you have any ideas on how I can improve!)
