We understand tornadoes scientifically, but it still feels supernatural. The randomness makes it feel supernatural.
'Envy the Night' was my first stand alone, the first book I'd written in the third person and I loved the feel of that, and it was different but it was also the same. 'So Cold the River,' I knew, was going to be really different, and that's why I thought about doing it as a novella under a pseudonym, because I didn't want to damage my career.
In terms of characters I wish I had created - just because I haven't dealt with anything like them - I'm really impressed by characters who can endure over time, whether that be a long series run like a Harry Bosch, or a character who endures over generations and continues to please readers: Sherlock Holmes.
I would say of characters I've created, the one I've felt the most connected to emotionally was Adam Austin from 'The Prophet.' I think it was the connection to the idea that one decision you make innocently enough can have very serious, drastic consequences for someone else's life.
I'd worked at a small town newspaper, and I was thinking of all the strange stories that I had seen float through the newsroom in my time there that were dismissed as kind of amusing curiosities. Somehow from that I got to this idea of an eccentric alcoholic who built a lighthouse in the woods.
