ClubJade.net points us over to the SW.com forums where Sue Rostini briefly touched on the next Lost Tribe of the Sith installment from John Jackson Miller. Titled Purgatory, this 5th e-book tie-in to the Fate of the Jedi series will be released on Monday, October 25th. Sue also said that we should hopefully see some cover art at the main site prior to the release. We'll be sure to keep you posted!
As a bit of a reminder, we know that subsequent Lost Tribe of the Sith stories will have the following titles according to a SUVUDU timeline update from back in September.
Sentinel Pantheon Secrets
UPDATE:Starwars.com has updated with Purgatory cover art, a plot description and links to catch up on the previous four installments.
UPDATE #2: Book five of the Lost Tribe Of The Sith series, Purgatory by John Jackson Miller, is now available for free download at Starwars.com.
