It is always a great compliment when a reader finishes your book and asks, 'So when is your next book coming out?'
What is not so great is when you don't have a firm date to give them. Even though authors generally hate marketing their product, you can't help but realise you have lost a marketing opportunity by not having another product to offer an interested customer. I was interviewed recently for a newspaper article and the journalist was very interested to know when my next book would be published. Thinking on my feet I answered, 'Hopefully by the end of the year.'
