Death Force in Paperback

Death Force is out in paperback today. I was in London yesterday, and it had great positions in WH Smith at Waterloo and Charing Cross. It was prominently displayed at No 60 in the top 100 at the front of the shop. It's an amazing experience to see a book you've worked on displayed like that. Of course, now I'm worried about whether people will buy it or not....but that's better than worrying about why it isn't in the shops.
