I just finished listening to Master & Apprentice earlier today. Claudia Grey was such a huge find; I've really enjoyed every single Star Wars story she's written so far.
I have to say, I really like how they handle Star Wars audiobooks. Not only are the narrators high quality, but the productions incorporate music and sound effects that really immerse you in the story. I plan to go back and re-read all of the previous canon novels in audiobook form, as this was only my second one, after Dooku: Jedi Lost. (Although I'm not sure if that one counts as an "audiobook" since it was written as a drama meant to be performed.)
