Book excerpt: In 2016, Sarah Bolling places a memoir on an old chair in her office to be found upon her disappearance. In its pages she makes personal confessions, including the account of a forty-year-old clandestine relationship with her American history professor. But, most startling is her recollection of a three month journey during the winter of 1974-1975. Had Sarah's adventure been revealed during her long career as a respected historian it could have easily derailed her professional life or, if believed, created an upheaval in reality as we know it.
