The Ghost of Hannah Mendes (Paperback, 1st St. Martin's Griffin ed)

When Catherine da Costa, a wealthy Manhattan matron, learns she has only a short time to live, she realizes that her family tree will die unless she passes on its legacy and traditions to her granddaughters. But Suzanne and Francesca, beautiful young women caught up in trendy causes and ambitious careers, have no interest in the past. Catherine almost despairs until one night she is visited by the ghost of her family's anscestor, an indomitable Renaissance businesswoman named Hannah Mandes.
The ghost of Hannah Mendes encourages Catherine to use every trick in the book to coerce the granddaughters to journey across Europe and acquaint themselves with their roots. While the sisters honor their grandmother's request out of loyalty, they believe their quest is futile--until it starts to uncover ancient pages from Hannah Mendes's fascinating memoir, and brings new loves into their lives.
