Empire and Rebellion: Razor’s Edge is a novel written by Martha Wells, which is part of the Star Wars: Empire and Rebellion series. The story takes place before the events in Star Wars: Episode V The Empire Strikes Back. The novel was set to be released on November 5, but it was moved up to October 1, before being set as September 24, 2013. The audio version was narrated by January LaVoy. The paperback edition was released on October 28, 2014.
Wells finished the final complete draft of the novel on January 15, 2013 and sent it in to editorial on the eighteenth. Though she had an idea for what the title could be in the end, she did not have one cemented at any time during the writing process. The title was to be chosen by Lucasfilm Ltd., from either her ideas or something someone else came up with.
