Being the Vader fan I am, I long looked for this book, liking the idea of him having an apprentice and all that... only to be kind of bored. I understood long before I finally got it that it was based on the video game of the same name, and is focused on Starkiller and all that, but it was still kind of boring. And towards the end, even when this came out with pre-Disney spinoffs and the like, putting the Death Star in it just sounded wrong to the then canon as it was. So it was okay, but I'll wait a while before checking out the second part - especially since the way this one ended, it just doesn't sound like it needs a part two.
