Cheapjack,
Sorry not to respond to your email yet. Our dog had surgery on Monday and my girlfriend and I have been taking turns nursing her while trying to keep with up with our respective deadlines. As a result, I've fallen a bit behind in my emails . . . .
The short answer: no, you can't live on Trek novels alone. I need to write at least six to eight books a year to make ends meet and there aren't enough TREK slots available to keep me busy full-time. Right now, for instance, I'm working on projects for DC Comics, C.S.I. and Zorro, while keeping a close eye on the Underworld franchise. Meanwhile, I also work as a Consulting Editor for Tor Books, and write plenty of freelance advertising copy for Tor, Nightshade, Pocket Books, and other publishers.
Hope that answers your question!
What does that mean, consulting editor?
