Amazon has finally resolved whatever issues were delaying the posting of Lost Tribe of the Sith #5: Purgatory, so now all you Kindle-philes can see what you've been missing! Remember, it's free!
It is also available on the Sony eReader and from Barnes & Noble. You can also simply download the PDF from StarWars.com.
I'd delayed posting any notes on the story until after the Kindle release went online, so I suppose that's on my schedule for the near future.
