Inheritance is a 2011 novel written by American author Christopher Paolini. It is the fourth novel in the Inheritance Cycle.
The Inheritance Cycle was originally intended to be a trilogy, but Paolini has stated that during writing, the length of Brisingr grew, and the book was split into two parts to be published separately. Because of this, many plot elements originally intended for Brisingr are in Inheritance.Since the release of Inheritance, Paolini has expressed his future interest in expanding upon Alagaësia and the Inheritance Cycle. In an interview, he talked about a potential "book five," a prequel centering on Brom, and said that he has planned "around seven more stories set in Alagaësia — and one of those is in fact a series."
