Green Darkness

A NEW YORK TIMES BESTSELLER. Exploring themes of love, reincarnation and good vs evil, the action starts when a 1960s guru sends a troubled American woman back over 400 years into a past life to save her marriage.
Strange things are afoot after English aristocrat Richard Marsdon takes his new wife Celia, an American heiress, to his family home in Sussex. Richard acts out of character, and Celia is suffering a debilitating emotional breakdown.
A friend of Celia's mother, a wise, Hindu mystic, realizes the couple is haunted by an event from their past lives, and the only way to repair the damage is to send Celia back in time.
The heiress journeys back almost four hundred years to the reign of Edward VI and her former life as the servant girl Celia de Bohun-and her doomed love affair with the chaplain Stephen Marsdon. Although Celia and Stephen can't escape the horrifying consequences of their love, fate-and time-offer them another chance for redemption.
