The Stone Trilogy, livre audio

What is the secret of Ben Cruachan, the hollow mountain that towers above the small village of Taynuilt in Argyll? Has it anything to do with a cat which disappeared from the riding school or the appearance of a stray pony?

As a twelve year-old Jennifer Lindsay comes across the secret that will govern a part of her life well into her adulthood, only then will the mystery of Samantha, the cat, be solved for her broken-hearted owner, Alison, Jennifer’s cousin.

And what role does the piper play in all this? As he says later, “If all else fails, there’s always the music.”
