I saw this on SlickDeals.net, get a free Star Wars book “Legacy of the Force: Betrayal”) PDF, MP3, Kindle or Sony eBook through Tuesday, May 13, 2008. (If that link doesn’t work try this link).
It looks like it’s part 1 of a “Legacy of the Force” series that they’re trying to promote, book 9 comes out on the 13th. The series is supposed to cover a “new era in the Star Wars universe and features the beloved characters from the original trilogy, answering the questions of what happened to Han, Luke and Leia after the conclusion of Star Wars: Episode VI Return of the Jedi”.
