The Battle of Mindor is one of the great conflicts of the Galactic Civil War that has yet to be documented in a novel, but best-selling author Matthew Stover is tackling this conflict as the subject matter of his new Star Wars novel.
Due out in February 2008, Luke Skywalker and the Shadows of Mindor tells the tale of the Alliance's efforts to stop Lord Shadowspawn and his black-clad legions of shadow stormtroopers shortly after the destruction of the second Death Star. All the classic heroes return -- Luke, Leia, Han, Chewie, Lando, Threepio, Artoo and the pilots of Rogue Squadron -- in a thrilling adventure of good versus evil, with the fledgling New Republic battling the stubborn remains of a splintering Galactic Empire.
Matthew Stover is best-known for his acclaimed novelization of Revenge of the Sith, and his psychologically charged and challenging Star Wars novels Traitor and Shatterpoint. Luke Skywalker and the Shadows of Mindor is due out in hardcover in February 2008 from Del Rey Books.
To be honest, I've never heard of the Battle of Mindor Endor Shmendor, or "Lord Shadowmort", it seems a tad forced to me.
