I read the first four books of the series three years ago for the first time (I have not reread them since). I enjoyed it very much to learn about the world through Eragons and the other characters travels and eyes. Knowing beforehand what happens would take away some magic. But there is a lot happening in the story, so you might enjoy them nevertheless before you read on. The main story ends in the fourth book Inheritance.

I just finished The Foundation Trilogy by Isaac Asimov. It was an interesting read, but sometimes felt more like a lot of historical short stories that were connected to each other.

Now I am reading Murtagh, the fifth book in the Eragon series by Christopher Paolini.
