Jack 1939 by Francine Mathews

It’s the summer of 1939, and Europe stands on the brink of war. Twenty-two-year-old Jack Kennedy, the sickly son of the U.S. ambassador to Britain, is sent on a secret mission by President Roosevelt to gather intelligence across a continent collapsing into chaos. As he travels through London, Paris, and Berlin, Jack is drawn into a world of espionage, betrayal, and seduction—where every ally may be a spy and every truth a trap. Torn between duty and conscience, he must navigate the dangerous politics of a world hurtling toward catastrophe, all while discovering the strength and ambition that will one day define him. Jack 1939 is a riveting historical thriller that reimagines a young JFK at the dawn of history.
