This is a prequel to Blake's 7. It’s a straightforward, fast moving story of the origins of Kerr Avon. It begins before Avon’s birth and shows the family structure he was born info, in the strange repressive culture projected for the future in the Blake's 7 universe. 

In here are some of the characters a Blake's 7 fan will recall - Anna Grant, Avon's only love; Del Grant, her brother; and Tynus, Avon's good friend - or so he believes!

In a weird duel in the frozen North of their mother planet, two brothers fight a duel to the death - and Rogue Avon is slain. This, the Federation feels, spells the end to rebellion in the universe, and the status quo of peace without freedom can continue.

But they are wrong. The son of Rogue Avon, obviously an Earthling and entitled to return to his home planet, has sworn to his mother to avenge his father. He manages to return to Earth, and there manages to work out the inevitable conclusion to this ingenious and fascinating tale.

Terry Nation on reading this book remarked: 'Now I know why Avon was the way he was.'

Producer Peter Anghelides said: "The question on every fan's mind when the original TV series ended was: 'What happens next?' So it was an unexpected treat when Paul Darrow defied our expectations by writing a prequel!

"And apart from Terry Nation, himself a good friend of Paul's, who better than the man who played Avon himself to reveal the character's history? When the book was first published in 1989, Terry said: 'Now I know why Avon was the way he was.'

"The original novel has been out of print for well over thirty years. We decided it was time to make it available again, compellingly brought to life in a fresh new reading by the familiar voice of Alistair Lock."

Narrator Alistair Lock added: "Having been involved with the full-cast audios since 2012, I was honoured to be asked to record Paul Darrow's Avon: A Terrible Aspect.

"As well as Zen and Orac, over the years I have played or read in for every member of the cast, including Paul as Avon. So reading this novel, I had great fun finding a voice for all the characters in Paul's story, including of course the man himself: Avon. Well now..."
