Eldest

Things I had forgotten from 1st read:
How Tolkien wannabe Paolini is: very descriptive, creating languages and showing it off throughout the book...
How obvious are Saphira's comments. 
How Roran arc is much more interesting than Eragon's
How philosophical Eragon's training was. I have even highlighted to remember in the posterity.

Another thing I noticed is the bring up of people's prejudices against other races. I hope the next books will develop it better, it would be interesting.
