When I worked at The Independent newspaper, I had colleagues who would laugh and say that whenever they picked up the phone to my dad and heard his accent, they thought they were about to hear a five-minute warning to get out the building. People in Britain have always thought it acceptable to make racist remarks about the Irish. The prejudice underlying that supposed joke was everywhere.

Despite being from Ireland, I've always avoided writing about it, for two reasons. For a very small country, Ireland has produced an astonishing number of literary geniuses, and at some level I probably never felt, having left as a toddler, that I had the right to try and add my voice. That's part of it. But I also didn't want to write something that was the equivalent of the Irish theme pub. You find them all over the world. The idea of producing a novel that might replicate that type of ersatz really set my teeth on edge.

She has spent most of the day reading and is feeling rather out of touch with reality, as if her own life has become insubstantial in the face of the fiction she's been absorbed in.

The Chilean novelist Isabel Allende says there's no such thing as writer's block, you just need to live a bit more. I try to bear that in mind.

When my family moved from Ireland in the 70s, Britain was such a difficult place to be Irish. It was a decade of real social and economic upheaval in Britain. There were strikes, the three-day week, the oil crises, huge inflation, the winter of discontent and, what was it, four Prime Ministers? And relations between Britain and Ireland at that time were at an all-time low. I was born in the year of Bloody Sunday and of course the pub bombings happened in the mid-1970s.

Something that had an enormous influence over my relationship with language was my stammer. I had a really bad stammer in my childhood and adolescence, and that imbues you with two things. First, a hyper-sensitivity to grammar, because a stammerer will have problematic sounds, impossible verbal stumbling blocks. Second, writing is just such a joy when you have a problem with speaking. It's so astonishing to watch language coming out of your pen without any hesitation or dysfluency.

She wanted to say, no. She wanted to say, I have a son, there is a child, this cannot happen. Because you know that no one will ever love them like you do. You know that no one will look after them like you do. You know that it's an impossibility, it's unthinkable that you could be taken away, that you will have to leave them behind.
