Bestselling nonfiction writer Mitch Zuckoff appears at a signing event Saturday in Mystic's Bank Square Books - on tour behind his latest project, "13 Hours: The Inside Account of What Really Happened In Benghazi."

The book details the events when terrorists attacked the U.S. State Department Special Mission Compound and a nearby CIA station called the Annex in Benghazi, Libya. Six American security operators fought against the invaders in defense of Americans stationed there. Five of those soldiers were Zuckoff's sources for much of the material - and, according to press material for "13 Hours," none of them have been recognized because they're no longer in official government service.

Zuckoff's other titles include "Lost in Shangri-La" and "Frozen in Time."
