David and Andrew looked forward to their holidays at Rusty’s farm where exploring the labyrinth of underground caves was fun. That is, until the energy-generating windmill was built. Then the boys encountered a terrifying underground creature. Where did it come from? Are there more? Who – or what – will survive? This science-fiction thriller from Gary Crew – master of suspense – is about curiosity, adventure and overcoming fear. At a deeper level it is about collaboration, honesty and environmental responsibility.
