Aftermath, as the title suggests, will pick up immediately following Return of the Jedi, and delve into the events occurring after the Battle of Endor. It has also been revealed that critically-acclaimed author Chuck Wendig is writing the novel.
The novel will also form part of a trilogy and will introduce a new cast of characters along with familiar faces. It has also been hinted that some characters and locations referred to in the novel will pop up or have relevance to The Force Awakens.
As a life-long Star Wars fan himself, Wendig has said that he feels privileged to have been given the opportunity to work within the Star Wars universe on the novel, which is due for release in September 2015.
