I only realised after reading this that I had already heard the excellent audio adaptation which includes Sophie Aldred and Anneke Wills. The original book is very good too, and I think would be reasonably penetrable for someone who hadn’t previously followed the Bernice Summerfield stories. Nicely observed emotional politics between and among Benny and her students, and the various aliens with whom Benny’s ex gets them involved. To a certain extent I felt it was the story that Colony In Space should have been. A good one (only the second Benny novel I have read, the first being the equally enjoyable Walking to Babylon).
