The inheritance cycle has been and always will be my favorite. I read Eragon when I was 13 in Highschool and immediately fell in love. Eldest is my favorite because it shows the most growth in Eragon as a character and a rider.
I loved the book. Never fails to keep you gripped from beginning to end. The story makes you really want to believe in such fantasies and powers and the narrator executes his job so well it will make you feel as if you were living it yourself.
