Over the past couple of years I've had the occasional request from someone who says they enjoyed my first book, but can't afford the second one and could I send them a free copy. So far I always have done, simply because it is no real loss to me and I send it with a note saying that if they enjoyed it then I hope they will leave a review on Goodreads or similar. (Though to my knowledge none of them ever have). But just recently I've noticed an increase in requests and some of them are quite "cheeky". I love my readers and I don't want anyone to miss out, but where do you draw the line?
