Brisingr

Third book in the Inheritance cycle. Eragon and Saphira travel to the helgrind to destroy the Ra'zac. After he returns to the Varden,he heads to Farthen Dur where he supervises the election of the next dwarf king. He then travels to Du Weldenvarden. While he is there he learns his true father's identity and how Galbatorix continues to gain power. It ends at the battle of Feinster. I think it is a great book.
