The story is predictable, but still a good read. From the cover itself, read:
In Alagaësia, a fifteen-year-old boy of unknown lineage called Eragon finds a mysterious stone that weaves his life into an intricate tapestry of destiny, magic, and power, peopled with dragons, elves, and monsters.
It is inspired by Tolkien, a lot. I haven't read enough fantasy to point out other authors. But still fun to read.
I'm not in a mood to do much of a review; so lets just say that I liked the book enough to have great expectation from the next of the series [Eldest, due out somewhere in 2005, so I should read it together with HP6]. It is generally considered that writers get better with age [or at least with experience], so I can't wait for what's to come from one.
Note: I really like fantasy, should get my hands on more books.
