I really love 'The Windsors' - and I hope the royal family love it, too.

I knew I wanted to write about female friendship. I've got a few friends I've known since we were teenagers, who have spanned the decades, and I do find that a fascinating thing, that friendship can last that length of time.

I wanted to write a book about female friendship, because it's a constant that goes right through to the end of our days. Over time, romantic love changes and often becomes something different, but friendship stays pretty much the same.

If you'd asked me when I was younger what life would be like in my 50s, I'd probably have imagined someone like my grandmother. I'd have looked like a little old lady who went for a shampoo and set every week. But it's funny - when you get to your 50s it's not like that at all because apart from a few aches and pains, I feel like I'm in my 30s.
