After the war Eragon goes missing and Murtagh is determined to find his brother. However Eragon is afraid of what he has become and doesn't want to come home. So he stays away. But as strange occurrences happen in Alagaesia and people are coming back from the dead, both must challenge authority, and Jane and Alec must choose between Eragon, their new coven brother, and the Volturi.

Eragon and Murtagh often take things forgranted. They know that they'll be there for each other, but how many times do they actually say what's on they're minds? How many times do they actually say how much they care and worry, that they have brotherly love for each other? Still, they're brothers and best friends. But even familial relationships have their dynamics.

He was told his name wasn't Murtagh; it's Joshua. He was told Alagaesia wasn't real; it was an imaginary land. He was told that Thorn wasn't real; dragons don't exist. And he was told that his entire lifetime was a figment of his imagination; he has psychosis. But now Murtagh isn't so sure anymore. Who is he really?

Far in the future the riders discover Vancouver and Murtagh accidentally angers Liber8; they seek revenge. Kidnapped, Murtagh is forced to watch as Liber8 rips his family away from him and rewrites his past, creating a new war all aimed at harming him. But when a mysterious threat appears that Liber8 recognizes, he has no choice but to team up with them to save his broken family.
