The Dangerous Shore: How a Motley Crew of Scientists, Mobsters, Double Agents, Retirees, Volunteer Pilots (and a Boy Scout) Stopped the Invasion of America

Sara Vladic, New York Times bestselling author of Indianapolis, reveals the gripping, untold history of the United States under attack during World War II and the improbable patriots who stepped up to defend their country in her hour of need.

History books have told us, in the decades following World War II, that Pearl Harbor was the only major attack on the United States’ home front. But this is not the whole truth. In The Dangerous Shore, leading researcher and bestselling author Sara Vladic unveils a much different story, one hidden away in dusty archives and behind press embargoes: Throughout the Second World War, German U-boats presented a very real threat to America’s eastern coastline, destroying ships, landing spies, and planning assaults on cities. With the country’s attention focused on the European and Pacific fronts, the U.S. would have been left undefended, if not for a ragtag bunch of characters who rose to the occasion.

Comprised of misfits, rejects, and outlaws, this motley crew came from unexpected places. Among their ranks was the stalwart Gill Robb Wilson, leader of a barnstorming corp of volunteer civilian pilots; the brilliant Dayton engineer, Joe Desch; and the nearsighted yet ""clairvoyant"" Kenneth Knowles, commander of the Phantom Fleet, entrusted with ULTRA intelligence.

Meanwhile, the cooperation of Grace Buchanan-Dineen, a self-styled countess and German spy turned double agent, helped the FBI net even more spies. Notorious but all-American mobsters Lucky Luciano, Meyer Lansky, and Socks Lanza struck deals with Naval Intelligence and kept watch over critical ports. Together their efforts turned the tide of war at home and saved thousands of American lives.

A thrilling and eye-opening read, The Dangerous Shore leads you through American history like never before. The story is an ode to the bravery, loyalty, and patriotism of our most unsung—and unlikely—heroes.
