"Brisingr" Christopher Paolini

The book “Brisingr” focuses on the story of Eragon and his dragon Saphira as they continue their mission to overthrow the evil ruler of the Empire, Galbatorix. There is a struggle for power as the small country named Surda attempts to overthrow the larger Empire. Surda is supported by elves, dwarves, Urgals, and human rebels known as the Varden. The Empire is populated with large numbers of humans and they far outnumber Surda and its allies.
Eragon is one of the few remaining Dragon Riders, a group that governed Alagaesia in past times but was almost destroyed by a Rider named Galbatorix, who took control of the land. Galbatorix fears that a new Rider will rise up and take his position as King of the Empire. When he finds out about Eragon and his dragon, he sends his servants the Ra’zac after them in an effort to capture them. Eragon and Saphira are forced to flee from their home, and decide to join the Varden. After training with the Elves and learning about magic Eragon and Saphira contribute in two wars against the Empire in which they are victorious. While in battle he realizes that the younger enemy dragon rider named Murtagh seems to be stronger than him. Eragon and Saphira return to the Elves capital Ellesmera to train again. The elf Oromis and his dragon Glaedr reveal that Eragon's deceased mentor, Brom, is Eragon's father. Glaedr also reveals the source of Galbatorix's power which is Eldunari or heart of hearts. It is not a dragon's actual heart but an Eldunari allows the holder to communicate with or draw energy from the dragon it belongs to, even if the dragon is dead. Glaedr gives his Eldunari to Eragon and Saphira before they part.
Brisingr is told in third-person from the perspectives of multiple primary protagonists. These characters include the humans Eragon, Roran, Nasuada, the dragon Saphira, and the dragon Glaedr. The humans Galbatorix and Murtagh return as the primary antagonists, along with Murtagh's dragon Thorn. The main theme of this book is to never give up. Throughout the entire book Eragon and Saphira are faced with difficult challenges and they make it through by sheer determination. Eragon was forced to learn magic and all of his skills at a young age he had to learn the things other riders had decades to perfect in a couple years. He is thrown into battles and he faces foes far stronger than himself but he pushes himself to the limits and never quits.
