Star Wars: Force Unleashed II, by Sean Williams

In Force Unleashed II, an apprentice of Darth Vader (Starkiller), struggles with his identity (is he a clone, or the real Starkiller?) and his allegiance to both Vader and the Dark Side as he completes his training and sets out do destroy. Juno still has feelings for Starkiller, and is surprised to see him walk back into her life after witnessing what she believed to be his demise.
Many sci-fi books are adding a dash of romance, the author of this book did it with more finesse than Star Wars: ... Vortex.
