I don't actually have a one wellspring of inspiration. Though I'm most often inspired while reading - both fiction and nonfiction.

I wrote for years before I was ever published, and I don't think I could ever stop. That said, I was also a veterinarian before I sold my first book, and I still volunteer my time to help with animal welfare causes. So that is a career I would be happy to return to - while still secretly writing strange stories back in my doctor's office.

Whenever I start a novel, I'm always looking for two things: a bit of science that makes me go 'what if?' and a piece of history that ends in a question mark.

With two books a year, I don't have time for writer's block.

I subscribe to National Geographic, Scientific American, Discover, and a slew of other magazines. And it is while reading articles for pleasure and interest that an interesting What if? will pop into my head.

Throughout history, knowledge rises and falls, ebbs and flows. What once was known is forgotten again, lost in time, sometimes for centuries, only to be rediscovered ages later.
