Yes, fans of Christopher Paolini's Inheritance series rejoice! Paolini's publisher has announced that Book 3 in the series will be released on September 23, 2008. So far, Book 3 does not have a title. Wonder what it will be?
Paolini also revealed that the series will expand to include a fourth book. Apparently, Eragon's story could not be tied up in just one more book so Paolini will write a fourth. No release date or title for Book 4 was announced.
So, while you count the days until September 23 of next year, why not reread 'Eragon' and 'Eldest' to keep the details fresh?
