What I imagined doesn't require anti-gravity beams or anything too spectacular, just advances in analysing different genes, finding out what they can do and recombining them.

I do always know where I'm going in my books. I know the endpoint. I've written only two thousand words of my next novel but I know what the ending will be already.

Holman's world is a worst case scenario but it's healthy to examine extreme possibilities. If the technology that is used for genetic enrichment in Genus had been distributed equitably, across society, it could have been nirvana, a great world where people don't fear the diseases that we die from. The problems that arrive are more to do with resource hording than technology itself.

I'm a hardened atheist but I feel that we have an inbuilt need for God. If you eradicate religion, you end up with something terrible in its place, like the communist state, as in Russia or China, where the dictator becomes the messiah figure.

When I start writing for the day, I usually read aloud the chapter I'm working on. It gets me into it and illuminates mistakes. I'm very rhythm conscious and I do enjoy repetition.
