A Cambridge historian, Elizabeth Vogelsang, is found drowned, clutching a glass prism in her hand. The book she was writing about Isaac Newton's involvement with alchemy-the culmination of her lifelong obsession with the seventeenth century-remains unfinished. When her son, Cameron, asks his former lover, Lydia Brooke, to ghostwrite the missing final chapters of his mother's book, Lydia agrees and moves into Elizabeth's house-a studio in an orchard where the light moves restlessly across the walls. Soon Lydia discovers that the shadow of violence that has fallen across present-day Cambridge, which escalates to a series of murders, may have its origins in the troubling evidence that Elizabeth's research has unearthed. As Lydia becomes ensnared in a dangerous conspiracy that reawakens ghosts of the past, the seventeenth century slowly seeps into the twenty-first, with the city of Cambridge the bridge between them.
Filled with evocative descriptions of Cambridge, past and present, Ghostwalk centers around a real historical mystery that Rebecca Stott has uncovered involving Newton's alchemy. In it, time and relationships are entangled-the present with the seventeenth century, and figures from the past with the love-torn twenty-first-century woman who is trying to discover their secrets.
A stunningly original display of scholarship and imagination, and a gripping story of desire and obsession, "Ghostwalk" is a rare debut that will change the way most of us think about scientific innovation, the force of history, and time itself.
