The Book series, published by Obverse Books, looks in detail at the making of individual Doctor Who stories. The 16th in the series, investigating Full Circle, was written by John Toon and published last year.
Editor Philip Purser-Hallard said
Both of John's books for the Black Archive have been a joy to edit -- really sharp and clear-headed, approaching the Doctor Who stories they analyse from fascinating angles. This recognition of his work is well deserved.This is Toon’s third SJV Award, having previously won for the award for best fan writer in 2013 and 2016, but this is his first award in a professional category. Asked about this victory, he said
This thrilling win - against strong competition! - wouldn't have been possible without Phil's editorial input, Blair and Cody's stylish cover design and Stuart's professional touch. They all deserve credit for this award, although I'm sure they'll understand that I'm totally keeping the trophy!
