Crossroads

Set after Revenge of the Sith:

Three years after the fall of the Jedi and democracy in the galaxy, the Empire reigns. Any remaining Jedi are spread across the galaxy, deep in hiding. Rayya Sena, a Jedi who escaped the infamous Order 66, is captured and taken to the dreaded Death Star. She is brought before the Emperor for execution, a fate every captured Jedi before her has befallen. But her life is spared.
Spared by the very person who has hunted her and many other Jedi across the galaxy-- Darth Vader. Sensing a darkness buried deep in Rayya that mirrors his own, Vader seeks to train her in the Sith. With Rayya by his side, the Empire would be unstoppable and able to squash the remaning resistance against them. Rayya must now learn and fight for the one thing she has sworn to destroy, or die.
But when the lines start to blur between master and apprentice, when Rayya starts to see the true man beneath the evil exterior, she arrives at a crossroads in which she must decide which side of this war she wants to fight for. And who she really is.
