Where did you get the idea for your most recent book?
I am lucky in that I live in an area with two major universities within 20 minutes of my house. So there are a lot of interesting speakers and events I get to attend. A couple of years ago I attended a talk by Dr. Ron Mallet, a physicist from UConn, on time travel, and his new memoir--when he was a kid his dad died suddenly, and he decided to become a scientist, invent time travel, and go back and save his dad's life. His story stayed with me--the whole what-if, universal dream of a do-over in which we DON'T lose a loved one. But of course, it never works out quite like our dreams. Endless stories are possible from this familiar idea, and Tesla was born of it, certainly.
