Earlier today, we briefly reached an Amazon UK ranking of 3996 (for all I know we may have peaked even higher).
We're falling back again now, but that's a very healthy ranking, especially for a book that won't even be published for a couple of months. The publicity from the interview with Viktor Nagornyy must have had an impact - Ophelia Benson has given the interview a couple of mentions over at Butterflies and Wheels, and the link from Richard Dawkins' site probably helped a lot. Thanks to all concerned.
We peaked at about 100,000 on Amazon the other day. Even that's not bad for a book that won't be published in the US until October. Again, we've slipped back now ... but the signs are hopeful that 50 Voices of Disbelief will attract some interest.
