Query: Very nice.

If a film company had to chose one of the new line of Dr. Who books to make into a movie, this would be the one I would chose. There's suspence, a gripping story line and a massive alien structure which has to be could, hadn't it? The only problem I have with this book is the end, I didn't quite get why everyone was turning into ghosts, and a time paradox turns up, which couldn't possibly happen in the real world. Appart from that, this book is a real winner.
