What have you been up to lately, and what are you working on next?
I'm just finishing up an economics textbook, and then I look forward to starting the fourth novel in my Life and Travels of da Vinci series. So far I've been averaging about one novel per year on da Vinci. I don't know how long the series will be when I finish it, since the first two books, Leonardo the Florentine and Leonardo: Masterpieces in Milan each covered decades of his life, and the latest one, Leonardo: To Mantua and Beyond, only covered six months of his life.
Who are your favorite authors?
I love to read and write historical fiction, so not surprisingly my favorite author is Jeff Shaara. His are among the few books that I will actually rush out and pay full price for when they come out. I think historical fiction is a great way to learn about history, and I hope that my historical novels will succeed in having even a portion of the influence on others that Shaara's have had on me.
