- "We've signed Paul Kemp up for a duology -- I don't have any other information I can reveal at this time."
- ―Sue Rostoni
On September 24, 2010, Sue Rostoni announced on the StarWars.com message boards that Paul S. Kemp had been contracted to write the duology, and on September 28 she confirmed that the novels would be released in hardcover.
On June 27, 2013, Kemp verified during his Reddit "Ask Me Anything" that the duology was on "standby" as a result of the Disney–Lucasfilm Ltd. deal and the impending Episode VII The Force Awakens. It was later announced on April 25, 2014 that Kemp was writing a new novel, Lords of the Sith, scheduled for a March 2015 release.
