The seed for my novel 'Half Brother' was planted in my mind over twenty years ago, but didn't germinate until late 2007 when I came across the obituary for Washoe, an extraordinary chimpanzee who had learned over 250 words of American Sign Language.

The more I worked on 'Half Brother,' the more it seemed to me the story was really about love in all its possible forms - how and why we decide to bestow it, or withdraw it; how we decide what is more worthy of being loved, and what is less. We are masters of conditional love.

When I'd written my 'Silverwing' series - I'd imbued the bats with full human awareness and vocabulary.
