When author Max Gladstone first read Updraft, he contacted me, saying “You know, there’s no magic in your book, only engineering.”
He had no idea how much I was going to use that phrase. I think I owe him lunch or something.
But he was exactly right, except that he was also wrong. There IS magic in the Bone Universe series—all the way through from Updraft to Horizon. And—from the bridges to the wings and more, to the understanding of the wind around the towers—the magic is all engineering.
