I recently went to the launch of Us Karen – it was huge. There were over 300 people there and around 300 books were sold. Wow. And I realised that the secret to its success was largely down to the subject matter. The author, Richard Dove, had chosen to write about an oppressed ethnic minority – the Karen people of Burma. So I’ve done the same thing, only I’ve written about New Zealanders, a people forced to leave their homeland to come to Australia and live on the dole.
