Instead of having fun on a school field trip, thirteen-year-old Andrea has to spend the weekend with her family at a boring wedding in boring Moose Jaw. Stories of gangsters, gamblers and greed don’t even sound that interesting.
Then Andrea accidentally falls into a mysterious tunnel and discovers she’s travelled back in time to the 1920s – those dangerous days of the city’s underground.
How will Andrea outsmart the gangsters who are demanding that she work for them? And will she ever see her family again?
