My book has a very simple surface, but there are layers of irony and paradox all the way through it.

Books are like people. Some look deceptively attractive from a distance, some deceptively unappealing; some are easy company, some demand hard work that isn’t guaranteed to pay off. Some become friends and say friends for life. Some change in our absence - or perhaps it is we who change in theirs - and we meet up again only to find that we don’t get along any more.

I've worked in television long enough to know that when you stop enjoying that type of thing you go home and do something else.

Find the extraordinary inside the ordinary.
