Past and present collide in richly mysterious Egypt, where recently divorced Anna Coburn is retracing a journey her great grandmother Louisa made in the 19th century. Cruising down the Nile from Luxor to the Valley of the Kings, Anna carries with her two mementos: an ancient Egyptian scent bottle, and the diary of that original Nile voyage, which has lain unread for a hundred years. As she follows Louisa's footsteps, Anna discovers both the chilling secret of the bottle and the terrifying specters that pursued her great grandmother.
