It was difficult to enjoy the trees and flowers when I was so aware of all that I had not yet done - pruning, weeding, transplanting, mulching, composting, tagging. When I was doing the work myself, I was happy, free.

There is nothing wrong with a writer who has a distinct style in book after book, but I am not interested in repeating myself.

A novel, for me, relies on my imagination to inspire your (the reader's) imagination. It is not all there for you. My novels or my stories come to me visually. I use words to translate the novel I see inside my head into words that I hope will create a movie inside your head.

A wife who loses a husband is called a widow. A husband who loses a wife is called a widower. A child who loses his parents is called an orphan. There is no word for a parent who loses a child. That's how awful the loss is.

A movie can evoke feelings, thoughts, it is all there and happening, there is no control over the images when you are watching a movie. You are transported for three hours to a world where you see real people. In a novel it is private - there's only you, and words on pages. The landscape is in your mind and in your feelings.

As a writer I am proud that if you took my last four books, and they didn't have my name on them, I don't think readers would know they were by the same author.
