Servalan first wowed viewers with her stylish evening gowns, close-cropped hair and ambitions of power during the TV show’s first season in 1978. She went on to become a staple of the series over its four series, always plotting to bring down Blake, Avon and the crew of the Liberator.

Servalan will make her first appearance in Wolf by Nigel Fairs on Volume 2 of The Liberator Chronicles, which is released in August. The story finds Cally on a mission to discover what happened to the respected Auron scientist Gustav Nyrron (who appeared in the Volume 1 story Solitary) – and only Servalan knows the answer.

Wolf also stars Jan Chappell as Cally, while Anthony Howell (Foyle’s War) will be reprising the role of Nyrron.

The three-disc box set also includes The Magnificent Four by Simon Guerrier, which reunites Paul Darrow and Jan Chappell as Avon and Cally, who are abducted by a team of rebels that have stolen another ship from The System.

False Positive is by Eddie Robson, and stars Gareth Thomas as Blake and Beth Chalmers as Lian. Blake is under psychiatric evaluation on an alien planet – are his stories of subversion and rebellion just the ravings of a delusional mind?

Volume 2 of The Liberator Chronicles will be released in August 2012.

A range of new Blake’s 7 novels also launches in May 2012 with The Forgotten by Cavan Scott and Mark Wright.
