The first book of the Riftwar Saga often was splited into two parts: Magician Apprentice and Magician Master.
Alright, Pug the slow learning (untrue) magician apprentice lives in a world called the ... we'll just call it the kingdom. One day they sensed some weirdo sneaking around their land and mapping it. They soon found out those weirdo are from another world coming through a rift.
They suspected a war... and there goes a a war.
By now, the retard (totally untrue) magician apprentice Pug ... is still a slow learning (so untrue). No, nothing magical had happened to him at the beginning of war that'd make him a hero.
So they fight... then Pug got captured and worked as a slave in the other world. (Yes, by now he still is a ... you know what I'm gonna say - so untrue).
The war went on for years... by chance, he became a powerful magician over in the other world. How it comes to that stage, you'll have to read the book.
Different world, different culture, different thinking and learning. If you think yourself is highly civilized, then you'd suspect the others are barbarian. The truth is, you just don't understand their culture and teaching that's all. They may think you're a barbarian by doing something your way as well.
It's a pleasure to read, however the "love" side in the stories are left quite untouched. I guess it's not the whole point in the book, but I thought if he can touch up on that bit would be great...
