End of the Saga
In this fourth and final book of the series, Eragon comes into his own as a dragon rider, discovers the truth about his lineage, makes peace with Murtagh and Roran, resolves his internal conflict over his attraction to Arya and learns to use understanding in an unconventional way in the final battle with Galbatorix.
Even more important the book goes on for several chapters beyond the end of the war where most fantasies would have ended. It looks at post-war chaos, devastation, confusion, and maneuvering in the power vacuum left after the conflict. Paolini has a deep insight into the aftermath of war far beyond the abundant hack and slash of battle of which there is plenty..
