Track your journey through the Nine Worlds! This challenge includes all published material in this universe, in the reading order on the author's website. Novels and novellas are added as main books, short stories and novelettes are marked as bonus. Book and story descriptions courtesy of the Nine Worlds wiki.

From the author: My Nine Worlds stories are set in various parts of the universe on both sides of the dividing line of the Fall of the Empire of Astandalas. They interweave and interconnect, so while you may certainly follow the internal chronology of the stories (see below), the suggested reading order begins with The Hands of the Emperor. Please note that you do not need to read each series in order! The Lays of the Hearth-Fire and the Red Company Reformed series, in particular, are thoroughly interleaved. 

You can also get a crowd-sourced opinion at the Nine Worlds wiki page! Please note that due to the nature of an encyclopedia, spoilers abound elsewhere in the wiki. (The reading order page is safe, however.)
