Thrawn trilogy

The Thrawn trilogy, also known as the Heir to the Empire trilogy, is a trilogy of novels set in the Star Wars universe, written by Timothy Zahn between 1991 and 1993. The first book marked the end of a notable drought of new Star Wars material over a four-year period, between the 10th anniversary of the original 1977 film's release and the release of Heir to the Empire (1991).
