Eldest picks up where Eragon left off, at the end of the battle between the Varden, aided by Eragon, Saphira, and their friends, and the evil emperor Galbatorix's forces in Farthen Dûr. With barely time to mourn his fallen friends Eragon is first caught up in political intrigue among the humans, and between the humans, elves, and dwarves, and then sent across the empire to complete his training as a Rider with the elves in the vast forest of Du Weldenvarden.
At the same time, Eragon's cousin Roran is sought by Galbatorix, who sends soldiers and two of the vicious Ra'zac to Carvahall, Eragon's home. Roran leads the villagers in holding them off, but Roran's fiancé is captured and the villagers are force to flee across the mountains, pursued all the way, to try to make their way by land and sea to Surda, the stronghold of the rebels.
As the story flips back and forth between Eragon and Roran we get to see both of them grow in maturity and power, Eragon as a result of his training with the last survivor of the old Riders, and Roran in a trial by fire as the de facto leader of his villagers fighting their way across the empire. These parallel streams, of course, converge in a climactic battle which once again ends the book.
