Perri O’Shaughnessy

Perri O’Shaughnessy is the pseudonym used by the writer sisters named Mary and Pamela O’Shaughnessy from The United States. They are the New York Times bestselling authors of mystery and thriller novels and are highly popular for writing and publishing the Nina Reilly series. The two sisters have particularly used the pen name, as an homage to a forgotten writer who was not able to get any client during his time. Also, it depicts the merger of the first names of the writer sisters, Pamela and Mary. The surname used in the pen name is the paternal name of the family of the two sisters. The O’Shaughnessy sisters hail from North Carolina, United States. Before going on to become full time writers and forming a pair, the two sisters completed their graduation. Pamela completed her graduation from the Harvard Law School and served as a trial lawyer for a total of 16 years.
