I have no idea where this author went to, I've never even talked to him.
His stories are different. Hammingbyrd is pretty obviously a mathamtician, or more probably some kind of geometry savant.
The way math and geometry permeate his stories give them a distinctive edge somehow. No other author can recreate that. Then it switches to a narrative that is crisp and perfect and you are right back into the story.
It's strange, and wonderful. I'm re-reading Preacher Man and the concepts are astounding to this day, and most of us authors wish we had come up with those ideas first.
The math is like friggin Chinese algebra. The sex is a bit clinical. But Holy Shit! The story idea is awesome.
