Starfire Trilogy

A fisherwoman finds a dead man on a tiny offshore island, with no clue about how the man got there. 

A camel driver deep in the northern desert rescues a man who speaks no known language, but is clearly well-educated. 

An ancient sect that was considered close to extinct sucks in all the land's young people and creates tension that may well lead to a civil war. 

And the old astrologer to the court, a weaselly and much-maligned relic of old times, might have hidden, for twenty years, evidence that those things are connected. 

An epic saga of magic-turned-technology, power and discovery.
