'The world has teeth and it could bite you with them anytime it wanted. Trisha McFarland discovered this when she was nine years old. Lost in the woods.'

Trisha has only veered a little way off the trail. But in her panic to get back to the path, Trisha takes a turning that leads into the tangled undergrowth. Deeper and deeper in the terrifying woods.

As darkness begins to fall, Trisha realises that she is not alone. There's something else in the woods - watching. Waiting . . .
