Not really my cup of tea - showing increasing acrimony amongst a group of five female hikers. There was I thought a group of male hikers too, what happened to them?. The Federal Police characters [Falk & Carmen] appeared very subdued with their contribution to the investigation. The theme of the story though was a great idea but I would have like to read more about past missing persons in the bush to add interest to the story. This book is all about peer pressure, personalities & family issues none of which I wish to know about. Sorry!
