Though Dave Duncan has been writing for eons, I never actually read any of his books -- perhaps because there WERE so many, and I wasn't sure where to start. So I seized on "King of Swords" as a good place to start, since it was the first book in a new series.
And it's a thoroughly solid start to the Starfolk series -- think a more science-fictiony version of those young-adult stories about half-faerie teenagers (usually girls) who discover their true nature. "King of Swords is written in a solidly average manner, with intriguing buildup, plenty of gusto and imagination.
Mira rescues a young boy named Rigel, who is not human -- he has no nipples or navel, and has pale eyes and hair. The only clue to his true nature is a silvery bracelet that serves as a sort of Spidey Sense. But he was raised by a human, so he doesn't remember a thing about his origins or even what kind of being he is.
But on a shopping trip, he and Mira are suddenly attacked by a mob -- and then spy a man who looks a lot like Rigel. Next thing they know, they have been whisked away to the world of the "starborn," elven aliens.
But the elf-aliens are not as welcoming as he had hoped -- he's a "halfling" whom they look down on, and he quickly discovers that their society can be cruel and uncaring, especially to earthlings. As he tries to navigate this strange new world, he falls in love with a princess he cannot have, and learns that he'll die soon if he doesn't escape the Starlands...
"King of Swords" is a hard novel to classify -- it dances between fantasy and sci-fi, adult and young-adult fiction. It reminds me of those post-Holly Black novels of teens finding out that they're actually faeries/half-faeries... except that in this case, the faeries are aliens, and tales of changelings and mythical beasts are actually derived from reality.
Dave Duncan's writing is a solid, workmanlike kind -- straightforward descriptive prose and dialogue, without many highs or lows. But he does throw a lot of wry, witty moments into the story, such as Mira's down-to-earth complaints (when she's stuck with the "mudlings"), or a Spanish-speaking Minotaur who really, really wants Rigel to kill him (instead of a "daffodil elf").
Flaws? Well, at times the Starborn's dialogue can be a bit clunky ("Desist, you groveling maggot. I do not wish to be embroiled in so sordid a contretemps"), and the mystery of Rigel's nature is revealed a bit too fast. It could have used a little more suspense.
We also could have used a bit more time to get to know Rigel and Mira before they are whisked away, especially for Rigel's sense of alienation. But Rigel is a pretty likable hero, who tumbles headfirst into a spiderweb of bizarre political trials and tribulations, and who is good-hearted and nice in a way that most of the Starfolk are not.
"King of Swords" is a solid, enjoyable sci-fantasy, mingling dragons and magic with alien elves -- it moves a bit too fast at first, but it has a lot to explore.
