Where did you get the idea for your most recent book?
The Huldufolk Chronicles was inspired by a photograph I saw on the Internet. The photographer was looking out from an elevated cave onto a horizon of plateaus stretching far into the distance. The sun is setting and the sky is an unearthly colour. It was mesmerizing, and it tripped that switch in my mind that sets off my "What if ..." mechanism. It took ten years of letting the premise simmer in the back of my mind before I was ready to turn it into a story, but it was worth the wait.
