How does inheritance by christopher paolini end?

SPOILER WARNING!*** They defeat Galbatorix. Nasuada becomes queen of Alagaesia (sp?) and Murtagh becomes good, because he falls in love with Nasuada. Roren lives and gets to be an Earl. They rescue a ton of hijacked dragon eggs and Eragon goes on to train a new order of dragons and riders. He and Arya go their separate ways and do not become a couple... very disappointing.
