Random House recently launched their new "Fricaya Network" site as part of the official Inheritance Trilogy website. The site, which in the future will house some information about Book 3, also allows you to email friends with a greeting card recorded by Christopher Paolini. Being a member also enables you to win some cool exclusive prizes, such as signed books, Eragon video games, and as a grand prize, a phone call from Christopher Paolini. You can sign up for the Fricaya Network here.
