War today is such a more visible thing. We see it on television, on CNN. In 1914, war was a concept. There was a naivety and stupidity that war would be a great lark.

It's not easy making a living as a writer, and for many years I worked at a Waterstones in Dublin. It was a good environment for an aspiring writer, with lots of events and authors appearing.

I like the idea of standalone novels. I always found with series of books, it's something that publishers love obviously because they can make a lot of money and they build an audience from book to book, but I don't like that as a writer. I prefer the idea of just telling a story, completing it within your book, and moving on and not forcing a child to read eight of them.
