This is one of the most interesting pieces of fantasy/science-fiction I’ve read recently. I’m sure I’ve mentioned before, in these book reviews, that I like world-building and systems of magic, and this delivers in spades. Magic, in Ra, is a type of engineering, and involves a great deal of math and rules and planning ahead. It’s a system to be uncovered, and scientists around the world are doing science at it, figuring out the rules. Why isn’t natural mana usable? What’s up with the weird dreams that all mages share? What happens to waste energy — magical friction — and why hasn’t anyone managed to detect it yet?
Basically, this is a book that takes solid aim at the mindset of someone like me, who will sit down and read through a veritable textbook on the workings of a magic system. And then, instead of just being a textbook, it comes with a whole story, that answers some of those questions in a way that makes for a solid story. (It helps that there’s a good amount of in-jokes for computer nerds — I mean, Wheel? That’s a neat touch.)
So, if you’re at all this sort of nerd, go give it a read. (You can also read it for free on the author’s website, but, y’know, pay people for their work.)
