It's always a little sad when you can tell the things the author finds the most interesting about their fiction aren't the same things you find the most interesting. I wanted a lot more of the blight and the powers and the zones and a lot less dogs talking to children.
He's intentionally trying to make the superintelligences stay superintelligent by not describing them. I think it's pretty effective. He did the same thing in Across Realtime.
His first book Tatja Grimm's World was also about superintelligent people (or the whole rest of the planet except them was sub-intelligent, or something… it's not clear). That one is, hmm, not nearly as good as his later ones. So I think it's just as well he didn't try.
