In addition to the "Republic Commando" Series, Traviss was one of three authors retained by Lucasfilm and Del Rey Books to pen a nine novel series called "Legacy of the Force" (the other two authors were Aaron Allston and Troy Denning). Her three contributions to the series are "Legacy of the Force: Bloodlines" (2006), "Legacy of the Force: Sacrifice" (2007) and "Legacy of the Force: Revelation" (2008). Thematically, her work within the "Star Wars" universe has frequently centered on Mandalorians and their culture. In particular, her "Republic Commando" novels have explored themes of identity with regards to clone troopers, their Mandalorian heritage, and their interaction with Jedi leadership. Traviss has since parted from Del Rey due to creative differences.
