I think it's only fair that I declare the competition closed now as I have had more entries than I have books to give away. There will be another competition on another blog next week, which I will give details of as soon as I have them. So if you are not a lucky winner this time, you will have another chance.
I am now going to sort through the entries and notify the winners. With any luck I will be posting the winners' names here later.
While we're on the subject of giving giving away free books...
I thought this was very interesting. My thanks to Mary Akers for the link.
