Professor Bernice Summerfield and the Crystal of Cantus (audio story)

Publisher's summary
Fabled crystals from long-dead civilisations. Jason Kane blundering into situations out of his control. Entombed Cybermen waking from a century-long sleep. It's all in a day's work for Professor Bernice Summerfield. Armed with her endless supply of witty quips and penchant for alcoholic beverages, she’ll find the Crystal, rescue Jason, destroy the Cybermen and be home in time for supper.

Except, this time, it's different. This time, as the saying goes, it's personal.

And, after this adventure, things will never be the same again.
