Steven and Yvonne visit their friend Max in a London hospital, only to be trapped inside the headquarters of an ancient Newtonian society.
Their escape with the Order's secret history sets them on a perilous adventure up the canals of England, pursued by a remorseless archbishop and his militia.
The best they can do for allies are a batty marquis and his wife, ex-convicts and an unreliable demon.
The book holds a great mystery to solve: but first they must survive.
