When Bobby Pendragon first arrives on the tropical world of Ibara, he finds paradise. As he works to uncover clues about the turning point this seemingly idyllic territory will soon face, all he can determine is that the people of Ibara are blissfully happy. It's not long before Bobby discovers, however, that they are also blissfully...oblivious.

The struggle of good versus evil continues as Bobby Pendragon follows Saint Dane to the territory of Zadaa. Saint Dane's influence has fueled the fire of discontent between two warring tribes: the Rokador and the Batu. This is also the territory where the Traveler Loor lives as a member of the Batu. Together she and Bobby must work to thwart Saint Dane's efforts to destroy Zadaa.

This is where it begins. The showdown for Halla. At stake is nothing less than all that ever was and all that will be. There's only one thing missing - Bobby Pendragon.

It has all been leading to this. Every victory. Every loss. All the thrills and sadness; the hope and despair. Bobby Pendragon's heart-pounding journey through time and space has brought him to this epic moment. He and his fellow Travelers must join forces for one last desperate battle against Saint Dane. At stake is not only the 10th and final territory, but all that ever was or will be. Everywhere.

Just when 15-year-old Bobby Pendragon thinks he understands his purpose as a Traveler - to protect the territories of Halla from the evil Saint Dane - he is faced with an impossible choice. The inhabitants of Eelong are in danger of being wiped out by a mysterious plague. Only Bobby knows how to stop it, but it means bringing the antidote from another territory - Cloral.

Fifteen-year-old Bobby Pendragon is a loyal friend, sports star, devoted pet owner - and Traveler. Along with his uncle Press, Bobby has visited the alternate dimension of Denduron and participated in a civil war. He's also waded through the endangered underwater territory of Cloral. Now Bobby once again finds himself thrust beyond the boundaries of time and space into a place that seems somewhat familiar: First Earth.

Fourteen-year-old Bobby Pendragon is not like other boys his age. His uncle Press is a Traveler, and, as Bobby has learned, that means Uncle Press is responsible, through his journeys, for solving interdimensional conflict wherever he encounters it. His mission is nothing less than to save the universe from ultimate evil. And he's taking Bobby along for the ride.

Bobby Pendragon is a seemingly normal 14-year-old boy. He has a family, a home, and even Marley, his beloved dog. But there is something very special about Bobby: he is going to save the world.

And not just Earth as we know it. Bobby is slowly starting to realize that life in the cosmos isn't quite what he thought it was. And before he can object, he is swept off to an alternate dimension known as Denduron, a territory inhabited by strange beings, ruled by a magical tyrant, and plagued by dangerous revolution.

Oaths sworn . . . loyalties tested . . . forces collide. Following the colossal battle against the Empire's warriors on the Burning Plains, Eragon and his dragon, Saphira, have narrowly escaped with their lives. Still there is more at hand for the Rider and his dragon, as Eragon finds himself bound by a tangle of promises he may not be able to keep.

Not so very long ago, Eragon - Shadeslayer, Dragon Rider - was nothing more than a poor farm boy, and his dragon, Saphira, only a blue stone in the forest. Now the fate of an entire civilization rests on their shoulders. months of training and battle have brought victories and hope, but they have also brought heartbreaking loss. And still, the real battle lies ahead: they must confront Galbatorix. When they do, they will have to be strong enough to defeat him. And if they cannot, no one can.
