Eldest is a fantastic book, with a spectacular story line. However, though it is
to be praised,
Eldest's plot is all to familliar. Those who have read The Lord Of The Rings will note that Eragon's fascination with Arya is similar to Aragorn's with Arwen. Also, the Elven princesses names are similar, just as Eragon's and Aragorn's are.
Eldests plot also borrows from Star Wars. The climatic ending of
Eldest which reviels Eragons father to be Morzan and his brother to be Murtagh is simmilar to the famous lines in Star Wars ; "Luke.
I am your father!!"
Ignoring the obvious plot similarities between the Lord Of The Rings, Star Wars,
Eldest is still an entertaning read, which is only marred by the great length.
