Elizabeth loves her job at the Manitoba Legislature building in Winnipeg, Manitoba. However, being marooned at work on the eve of the winter solstice due to a blizzard was not on her list of holiday events. The legislature building is full of mysterious symbols, hidden in plain sight. From the Bison to the Pool of the Black Star, there is more to the symbols than Elizabeth ever imagined. To her surprise she encounters another soul in the building with her. A mysterious man who says his name is Septimus. Together they must thwart a once every hundred year threat to the honesty and morality of those who pass through the doors of the legislature. Sacred Geometry, sacred numbers and a message only the Sphynx on the roof can supply.
