In the first post I posted some links to reviews of/articles about the series, but the best one, by Brian Sibley himself on his own Website, had been temporarily removed due to site being updated. I emailed Brian & asked when it was likely to reappear, & he's very kindly put it back up (sans pics for the moment). Anyone wanting more background on the series can find it here
