Mining the Genre Asteroid: The Argylle Series of Elizabeth Willey
The Kingdom has a problem. A set of problems, really. An untested young prince from a family of long-lived warriors and sorcerers has to deal with magical beasts mucking about in the great Forest near the city. A rather large Dragon has appeared, threatening to cut off a road to a nearby world. A hitherto unknown sister has appeared on the scene. A cousin from an old and still grudge-holding realm has popped up, too, seeking to establish relations, personal and diplomatic. It’s a lot on the plate of the young prince, and his siblings, who are trying to manage the kingdom as best they can. No one has any idea where their father, the ruler, or their uncle, the sorcerer, is. Oh, and the secret to the family power is a magical primal node of power in the Castle basement. Roger Zelazny’s Amber you say? You’d be forgiven for thinking so, but the prince is Gwydion, the power source is a Spring, the Kingdom is Argylle, and the author is Elizabeth Willey.
