The Sunken Gold: A Story of World War I, Espionage, and the Greatest Treasure Salvage in History (Chicago Review Press, 2017).

Seventeen Fathoms Deep: The Saga of the Submarine S-4 Disaster (Chicago Review Press, 2015).

“A worthwhile purchase for fans of such recent best sellers as Erik Larson’s Dead Wake and Hampton Sides’s In the Kingdom of Ice.” —Library Journal Xpress

“[Williams’] recreation of the S-4 disaster is absorbing, lucid and paced like a novel.” —The Day

“…the reader is plunged into a series of inspiring and heartbreaking adventures…. Although fresh national security scandals from Iraq to Benghazi have long since taken the place of the S-4, the story is eerily familiar. Williams’ new book goes a long way to remind those of us without security clearances — no matter how diligent the press — of the bravery and honor of those serving in our armed forces even under the most dubious clouds of conflict.” – Provincetown Banner

Four Years Before the Mast: A History of New York’s Maritime College (Fort Schuyler Press, 2013).

“Long overdue, Williams’s work contributes significantly to our understanding of maritime education in the United States…” Sea History Magazine

“…this book is not just for Maritime College graduates; it presents a pleasant combination of maritime history, maritime educational history, and sea stories…. Williams regales us with tales of heroism, adventure and tomfoolery…” Marine Technology (MT)
