The diagnosis was immediate: Masses matting the lungs and deforming the spine. Cancer. In my neurosurgical training, I had reviewed hundreds of scans for fellow doctors to see if surgery offered any hope. I'd scribble in the chart 'Widely metastatic disease - no role for surgery,' and move on. But this scan was different: It was my own.

I don't think even when you find a person, you can be completely honest, ever. There's still pieces of you that you don't give away. I do believe you always need that place where it's just you, your thoughts, no one else's judgment or anything.

My first draft is always way too long; my books start out with delusions of 'War and Peace' - and must be gently disabused. My editor is brilliant at taking me to the point where I do all the necessary cutting on my own. I like to say she's a midwife rather than a surgeon.
