Book recommendation: The Stay-Behind Cave by Boris Starling
Lord Of The Flies meets Flowers In The Attic. December 1940. As the German army closes in on Gibraltar, 16-year-old Rassie Elder and five friends stumble across the most secret place on the Rock. They were never supposed to know about this place, let alone find it. And now they're trapped inside, Gibraltar has fallen, and they'll stay alive only as long as they can remain undetected. But danger is not just outside the cave. It's in there with them too. For there is no darkness greater than that of the human heart. And the terror is just beginning.... The greatest World War Two story never told. Until now. Available from Amazon.
