Recently divorced, Anna Fox decides to cheer herself up by retracing a Nile cruise her great-great-grandmother, Louisa, made in the mid-nineteenth century. Anna carries with her two of Louisa's possessions - an ancient Egyptian scent bottle and an illustrated diary of the original cruise, a diary that hasn't been read in a hundred years. As she follows inLouisa's footsteps, Anna discovers in the diary a wonderful love story from the Victorian past - and the chilling, more distant secret of the little glass bottle. Meanwhile, two men on the cruise are developing an unfriendly rivalry for Anna's attention - and a disturbing interest in Louisa's things. Most frightening of all, Anna finds herself the victim of a threat that grows in strength and darkness as the dramatic stories from three different eras intertwine along the mysterious waters of the Nile.
