Elizabeth and McKenzie are roped into an adventure in Amarillo, Texas,
when a strange man shows up at the Big Texas Steak Ranch asking about
some missing marbles that were given to a waitress thirty years ago.
What could be so important about a missing bag of marbles? And why would
anyone be tracking them down so many years later? Elizabeth and
McKenzie, along with help from the other Camp Club Girls, will soon find
out!
