When it is going well, it is the best job [writing] in the world. For those few hours, you are god, in control of everything. However, for me, the great joy of writing is that it has allowed me to travel the world in search of stories.

I was brought up in a home where I saw my parents read and I was taken to bookshops and libraries, so I grew up feeling very comfortable around books. Also, Ireland is a country which has honoured its writers and poets, so when someone says they wanted to be a writer, its not mocked or looked down upon.

A good story is always a journey. It is about taking the journey, the people the hero meets along the way and how they change him or her. All stories are journeys. They don't have to be shocking or outrageous: they simply have to be interesting.

He who retreats lives longer.

I was born and raised in Dublin, Ireland and it is still home to me. My writing has taken me all over the world, but this is the place I come back to and the place where I find it easiest to write.

There really is no difference in the actual writing or plotting. I choose to tell different stories for the younger reader and, of course, I would never put sex and extreme violence in a YA book. But writing for adults and children requires the same care and attention.
