One of the pitfalls of writing about illness is that it is very easy to imagine people with cancer as either these wise, beyond-their-years creatures or else these sad-eyed, tragic people. And the truth is people living with cancer are very much like people who are not living with cancer.

We don't tend to write about disease in fiction - not just teen novels but all American novels - because it doesn't fit in with our idea of the heroic romantic epic. There is room only for sacrifice, heroism, war, politics and family struggle.

There is a lot of talk in publishing these days that we need to become more like the Internet: We need to make books for short attention spans with bells and whistles - books, in short, that are as much like 'Angry Birds' as possible. But I think that's a terrible idea.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.
