Knopf Books for Young Readers, the publishing house behind the Inheritance Cycle, has worked with Christopher Paolini to create an enhanced e-book of Inheritance, the final book in the series.

The enhanced e-book includes 17 videos of Paolini’s behind-the-scenes commentary embedded throughout the text, plus the author’s never-before-seen artwork, a letter to fans, and a new scene within the text. Also on October 23, Knopf will release the Inheritance deluxe edition in hardcover ($29.99), the Inheritance trade paperback ($15.99), and the Inheritance Cycle trade paper boxed set ($54.96). These follow the November 8, 2011, publication of Inheritance, which set a record for highest first-day sales in 2011 of any adult or children’s title, moving 489,500 copies in print, digital, and audio formats.
