Book of Sith: Secrets from the Dark Side is a reference book on the Sith Order and the dark side of the Force by Daniel Wallace. It was released on February 10, 2012 bundled with a collector's case and additional items. It was released on April 16, 2013 without the case or additional items.

The book was released again in August 2014 as part of a Deluxe Box Set with The Jedi Path that included two art prints depicting figures from Sith and Jedi history, and again in September 2016 as Star Wars: Secrets of the Galaxy Deluxe Boxed Set with the Imperial Handbook and Bounty Hunter Code

The black-and-red pyramid-shaped Sith case appears innocuous. But with the touch of a button, the door of the case lifts, accompanied by lights and Star Wars sound effects. The secrets within are revealed—the Book of Sith slides into view.

The book and its Sith holocron

The Sith have existed in the galaxy for centuries, lurking, waiting for their chance to seize control. As various Sith Lords emerged and rose to power, they recorded their thoughts, exploits, and plots for Sith control of the galaxy. When they fell, their knowledge vanished with them forever. Or so it seemed. . . .

Over the years, these writings were passed among numerous Sith and Jedi, who added their comments to the pages. In his quest for domination, Darth Sidious tracked down what remained of five pivotal Sith texts written by his most powerful predecessors. Then, drawing on the knowledge within the compiled pages, he wrote a sixth text—his own manifesto. Together, these documents, along with several collected objects associated with them, shed light on the philosophy, achievements, and failures of the Sith Order.
