Escape to Yackandandah

Two young ladies excitedly leave school just before Christmas to enter the work force. As teenagers, they do the usual things that teenage girls do. A summer rock concert in particular was a "must do".
Then they disappear. No one knows how, when or where they have gone except the matronly police officer and two undercover agents.
The story unfolds with its twists and turns and things that we often experience in Australia. And, of course, some romance.
