Unlike most of the others here, I have never heard of Mr Miller or read any of his books.
Anyway, I'm toying with the idea to get "Star Wars Lost Tribe of the Sith: The Collected Stories
to get a feeling for JJM's writing, so I have a question for those more in the know:
It seems like those stories are stand-alonish, although they seem to be a prequel to a novel series. Am I understanding that right, or would you say it wouldn't make much sense to read that book without knowing Fate of the Jedi?
You don't need to know anything about the Fate of the Jedi
series to read Lost Tribe
. The stories collection provides a backstory (set over the course of 5,000+ years) for the Lost Tribe of the Sith and what makes them different from other takes on the concept.
ETA: And like I mentioned earlier, having read it, I definitely recommend the collection.
