In Portland OR there’s the legendary Powell’s Books. They have new and used books and their magic section always has something of interest to me! Last time I was there I picked up the book Magic in Theory by Peter Lamont and Richard Wiseman.

This book is interesting in that it breaks down magic to step by step actions and explains those actions. I’m only on about page 50, so that’s what I’m getting so far.
This book isn’t specifically written for magicians, so it’s a bit clunky as they try to not reveal methods. I think the book would be better if it was written for magicians, or for non-magicians, but trying to straddle that line I feel makes the book not quite hit as hard as it could. There’s great information in it that’s dumbed down so low that I think magicians would gloss over some of the authors observations.
It’s a good read and a deal at what I paid for it as a used book. So far, it’s worth a peek if you can find a cheap copy!
