"Wizard World" is actually "changeling" and "Madwand" combined.
In "changeling" we reveal that Pol Detson , a son of a sorcerer , and Mark Marakson , a son of Our-world-computer-genius , have been switched when they were babies in order to prevent the murder of the sorcerer's son.
Mark grows in a world that chose to go in the ways of magic, but his mechanical talents are strong within him. He doesn't care about the reaction he gets from his surroundings, until he's almost lynched, and vows to get revenge.
Pol detson , meanwhile, is in our world. He is an artist, a musician, a guy with a free soul and feeling he doesn't belong.
Since childhood, he had a white streak going trough his black hair. He has mild telekinetic powers, and while playing he sometimes build castles and dragons and such from smoke.
The day comes, when Mark, with the help of ancient technology, is becoming a real threat to the delicate balance in his world. The only way to stop him is to confront him with Pol.
Pol is hauled into this world of magic by the old sorcerer that made the switch to begin with, and is amazed. He is in the land of his dreams.
Being from a long line of sorcerers his powers grow. When he is recognized as belonging to that lineage he is almost lynched himself. Even though he's been treated horribly he decides to confront Mark Marakson for the protection of civilization and to guard the status-quo between technology and magic.
In "Madwand" Pol lives in his father's castle and is studying sorcery. He is a Madwand - that is, a natural magician, but he too can learn a lot in matters of technique.
I can't reveal the plot since it's a story about how Pol is driven into the schemes and plots of the sorcerer's guild, and finds out details about his lineage and father.
In this books you will find a marvelous interpretation of magic - a combined hallucination, based on telepathy, that makes all the "fireworks" in a struggle of will-power between psyonic people.
Off course, when you read about Pol's "second sight" (the way he sees magic) and follow him in his understanding that every sorcerer sees magic differently, it's a little more exciting than reading it here.
I gave the book only four stars because I can't compare it to "Lord of light" or "Creatures of light and darkness" - those are 5 star books, but it is a very good fantasy non-the-less.
