Star Wars: Lost Tribe of the Sith: Secrets by John Jackson Miller

In Sith teachings, nothing is more important than the individual: the glorious center of the universe, around which all other lives pale in importance. But the planetary home of the Lost Tribe of the Sith is not the center of the universe, but a backwater — and the tribe’s legendary founders were little more than slaves themselves!

When the Lost Tribe suddenly rediscovers its forgotten origins, frustration and anger threaten to finish the society once and for all. But the past holds more secrets still — knowledge that, in the right hands, could place the evil rulers of Kesh on a path toward a greater destiny in the stars…

The free eBook will be available in all eFormats on March 5, 2012 and will feature an excerpt from Star Wars: Fate of the Jedi: Apocalypse, the final installment in the epic Fate of the Jedi series.

Star Wars: Lost Tribe of the Sith: The Collected Stories by John Jackson Miller

At last, collected in one volume and available in print for the first time, the eight original installments of the epic Lost Tribe of the Sith eBook series… along with the explosive, never-before-published finale, Pandemonium—more than one hundred pages of new material!

Five thousand years ago. After a Jedi ambush, the Sith mining ship Omen lies wrecked on a remote, unknown planet. Its commander, Yaru Korsin, battles the bloodshed of a mutinous faction led by his own brother. Marooned and facing death, the Sith crew have no choice but to venture into their desolate surroundings. They face any number of brutal challenges—vicious predators, lethal plagues, tribal people who worship vengeful gods—and like true Sith warriors, counter them with the dark side of the Force.

The struggles are just beginning for the proud, uncompromising Sith, driven as they are to rule at all costs. They will vanquish the primitive natives, and they will find their way back to their true destiny as rulers of the galaxy. But as their legacy grows over thousands of years, the Sith ultimately find themselves tested by the most dangerous threat of all: the enemy within.

As the description mentions, this paperback edition will feature an all new novella length story also written by John Jackson Miller and will be available on July 31, 2012. More info here!
