Gunn Memorial Library in Washington will present a book talk and signing with Mary R. Morgan, author of "Beginning with the End: A Memoir of Twin Loss and Healing," Nov. 1 at 6:30 p.m.

In the winter of 1961, Ms. Morgan was 23 and had a new job, a new husband, and a sheltered, privileged life as a member of the Rockefeller family; specifically she was the daughter of Nelson A. Rockefeller, governor of New York.

But tragedy changed her life forever when her twin brother, Michael Rockefeller, disappeared off the remote coast of New Guinea while collecting oceanic art for a New York City museum. He was never found.

The book begins with Ms. Morgan's and her father's search for Michael and recounts Ms. Morgan's 27-year emotional denial of her brother's death and repression of her grief, which controlled her life and relationships.

Later in the book Ms. Morgan shares the meaning and dynamics of moving forward with her life.

Through her personal and professional experiences as a psychotherapist, Ms. Morgan discusses her work with the twin survivors of the 9/11 World Trade Center disaster and the healing benefits of imagery developed from the work of Carl Jung.
