Gilmore Girls meets Oppenheimer in this dual-timeline family saga, set in a Manhattan Project town, about a granddaughter who uncovers her grandmother’s nuclear-age secrets and her own toxic inheritance.

What is the half-life of O’Toole family secrets?

In 2013, Saige is stuck living with her Granny Rosamond in her beige wasteland of a hometown. Desperate for a diagnosis and cure for her mysterious ailments, she uncovers more than she bargained for—a hot rock that shouldn’t exist and a past Rosamond refuses to explain.

That past takes place in the 1940s, when 50,000 people move to an eastern Washington town that doesn’t exist to build something they can’t name. Rosamond is one of them, eager to do her bit for the war effort—and find a husband. When she falls for a charming engineer, she envisions a perfect life. But as the hot war turns cold and her ever-expanding family becomes increasingly troubled, she discovers this nuclear town is no utopia, and she must decide whether to cling to the destructive facade of domestic bliss or face the truth that could save them all.

When Rosamond’s past collides with Saige’s search for healing, half-buried secrets—from the most contaminated place in the Western Hemisphere to the wounds within their own family—can no longer be ignored. Can Saige discover the truth and heal herself without destroying her grandmother’s life?
