Book excerpt: The village of Marsdale is a quiet corner of the world, cradled in a remote dale in England's lovely Lake District. The rhythm of life in the deeply religious, sheltered community has not changed for centuries. But in 1936, when Waterworks representative Jack Ligget from industrial Manchester arrives with plans to build a new reservoir, he brings the much feared threat of impending change to this bucolic hamlet. And when he begins an intense and troubled affair with Janet Lightburn—a devout local woman of rare passion and strength of spirit—it can only lead to scandal, tragedy, and remarkable, desperate acts. From Sarah Hall, the internationally acclaimed author of the Man Booker Prize finalist The Electric Michelangelo, comes a stunning and transcendent novel of love, obsession, and the passing of an age.
