‘I am an engineer and a measured man of the world. I prefer to weigh everything in the balance, to calculate and to plan. Yet my own heart is going faster than I can now count.’ In 1649, Jan Brunt, a Dutchman, arrives in England to work on draining and developing the Great Level, an expanse of marsh in the heart of the fen country. It is here he meets Eliza, whose love overturns his ordered vision and whose act of resistance forces him to see the world differently. Jan flees to the New World, where the spirit of avarice is raging and his skills as an engineer are prized. Then one spring morning a boy delivers a note that prompts him to remember the Fens, and confront all that was lost there. The Great Level is a dramatic and elemental story about two people whose differences draw them together then drive them apart. Jan and Eliza’s journeys, like the century they inhabit, are filled with conflict, hard graft and adventure – and see them searching for their own piece of solid ground.

Spanning several decades in seventeenth century Great Britain and America, this “impressive piece of work, rich in historical detail and human insight” (The Sunday Times) is an unforgettable love story exploring the power of nature versus man and man versus woman. I am an engineer and a measured man of the world. I prefer to weigh everything in the balance, to calculate and to plan. Yet my own heart is going faster than I can now count. In 1649, Jan Brunt arrives in Great Britain from the Netherlands to work on draining and developing an expanse of marshy wetlands known as the Great Level. It is here in this wild country that he meets Eliza, a local woman whose love overturns his ordered vision. Determined to help her strive beyond her situation, Jan is heedless of her devotion to her home and way of life. When she uses the education Jan has given her to sabotage his work, Eliza is brutally punished, and Jan flees to the New World. In the American colonies, profiteers on Manatus Eyland are hungry for viable land to develop, and Jan’s skills as an engineer are highly prized. His prosperous new life is rattled, however, on a spring morning when a boy delivers a note that prompts him to remember the Great Level, and confront all that was lost there. Eliza has made it to the New World and is once again using the education Jan gave her to bend the landscape—this time to find her own place of freedom. A “story of passion, possession, and a painful education in love” (Sarah Dunant, author of In the Name of the Family), Call Upon the Water is an adventure, an unusual and intelligent love story, and a powerful comment on the relationship between humans and the environment. “Richly involving…rousing and heroic” (The Guardian), this unforgettable historical novel is perfect for fans of Hilary Mantel, Geraldine Brooks, and Philippa Gregory. *Note: This book was published in the UK under the title The Great Level.

Much of eastern England is below sea level, resulting in wide swathes of marshland that are easily flooded. In the seventeenth century, the Bedford Level Corporation was set up by Francis Russell, fourth earl of Bedford, in order to manage the drainage of the Great Level of the Fens, which became known as the Bedford Level and is the largest region of fenland in eastern England. Between 1828 and 1830, Samuel Wells, the corporation's registrar, published his well-documented history of the Bedford Level and the attempts made at various points to clear it of water using a variety of methods, from earthworks raised by the Romans to the strategies of Sir Cornelius Vermuyden and the eventual introduction of steam-powered technology. Volume 1, published in 1830, contains a historical account of the area and of the commission set up to address the perennial problem of flooding.
