Sixteen-year old Celest Cain has honor of being the Rider of Fírek, the only hatchling of Saphira Bjartskular and Fírnen, and will soon have the privilege of leaving Oromis Isle to act as a full member of the order along with her two closest friends, Marilis Silvertongue and Halle Prince. However, before their graduation, Halle and Celest return to Alagaësia on a special mission to find the land caught between a political struggle. After scorning King Orrin's marriage proposal, High Queen Nasuada's life and country are at risk. Celest, Marilis, and Halle must join the other Riders and their dragons to put an end to Orrin's plot. But the question is not if they can succeed. Rather, it is if they will. *** Special thanks to @Nikkisha16 for all of her help with this description and other things.

Three years has passed since Eragon and Saphira left Alagaësia to venture out into the unknown. They have been to many new places, making friends and foes on their travels. But now a message from the elf Arya, the rider of Fírnen and a close friend of Eragon, requests them to return to their home of Alagaësia once more...

It has been quite a time since Galbatorix's death. Eragon has settled far away from Alagaisia and the Dragon Riders are restored. Soon, a new party of untrained dragons and riders arrives, and one of them seems strangely familiar...
