The most terrifying thing I can think of is being alone - and I mean utterly alone, like no one else in the world alone - at night. That's the nucleus of the first story in my collection and it's also where the title came from for the book.
I can look back at stuff I wrote in my early days and squirm at some of the mistakes I made. But we're all learning every day we never stop. I just hope people keep on liking what I do. That gives me such a kick.
