Fallout is a gripping Cold War–era domestic thriller that delves into the hidden tensions, loyalties, and secrets of American military families stationed in 1980s West Germany. The story blends coming-of-age drama with high-stakes suspense and rich historical detail.

For the military families who live in Benjamin Franklin Village, family life isn't just family life, but a vital front in the Cold War. It's a patriotic act, a performance of the American Way. They have backyard cookouts and go to high school football games and try to live like they aren't in a perpetual state of almost-war. They smile outwardly, join social clubs, and hide the unhappiness that goes on behind closed doors. That is, until the Vaughns arrive. Still reeling from the loss of her mother, sixteen-year-old Samantha Vaughn is a wild child looking for trouble, but when she finds it, her father's rank means she's the only kid who won't pay some kind of price for it. When her social circle shrinks overnight to prissy but pretty Becky Jennings and surly, antisocial David Williams, the frictions between the three of them turn to dangers that none of them recognize. For the women—sturdy, seasoned Army wives Madge Williams and Abby Jennings—Colonel Vaughn's second wife, Joanne, pulls them out of their '50s-era military culture and into the modern age. As a newly liberated Madge pushes at the boundaries of an unhappy marriage and Abby struggles to find her place in their changing friendship, Abby's tight grip on old loyalties keeps her from recognizing the threats circling her own family and her friend's. And when a mysterious package is left on the front step of one of their homes, someone won't survive the explosive fallout.
