Shock Wave by Walt & Leigh Richmond.
Thanks to a helpful Facebook forum member I was able to find out the name of the book and download it. I read it in one day, thanks to this being a sick day for me.
Shock Wave is one half of an Ace Double that I read when I was maybe 12 years old. The other Ace Double stories I read at the time were kind of crappy. But this one stood out in my mind as being well beyond the par.
I found the book here Publication Series: Ace Double
The first time I read this book I really didn't understand it. I would call it a college level read. Some of the terminology (such as "dry circuit") requires knowledge of electronics. Since I don't know any electronics jargon I had to Google "dry circuit." But when I was 12 I would have had to visit a resource library. But that was too much trouble, and there was a lot that I didn't understand in the book.
But it's not just a technical read, there's an interesting story and even a moral. So it has a little bit of everything. And it's really very complicated for an Ace Double. The other half of the book, called "Voyage to the Dog Star," was kind of dumb and forgettable.
With many decades of experience and learning under my belt, I finally understand the book.
