Word is Paul Kemp’s Star Wars: The Old Republic: Deceived about another Darth-somebody-or-other Sith warrior is the one to get, whereas longtime BioWare writer Drew Karpyshyn’s Star Wars: The Old Republic: Revan about a fallen jedi sounds like a miss (there’s also Star Wars: The Old Republic: Fatal Alliance if you want the full set). Then again, I’ve yet to read a franchise tie-in book that’s didn’t read like glorified fan fiction (be it the fault of the writer or a by-the-numbers editing team).
