Spoilers below, you have been warned:
It was way good, much better than I had expected! A touch derivitive mebbe, a hair predictable, but still great. Fighting, Fencing, Enchantments, Monsters, True Love, hidden identities... And Galbatorix finally had a line of dialogue!
I'm actually jazzed to get the next and final book. Will Roran wind up as the third Dragon Rider? I kept expecting that, but it didn't happen (sorry if I am spoiling anything, here for anyone who hasn't read the book). If not Roran, who? Arya? What about Shurikan? Is he evil or just a slave? What if it turns out that Shurikan is the evil mastermind and Galbatorix is his slave? I don't think it will play out that way, but it would be a clever twist. Third egg: is it a boy or a girl? Assuming Thorn survives and Shurikan dies, and the third egg hatches into a dragon, doesn't that make for an awkward love triangle amongst the three remaining dragons?
Anyhow. The 4th book probably won't come out for a century anyway.
