In the hills of Tennessee, two women work at a Manhattan Project site during World War II and uncover truths that irrevocably change their lives in this captivating new story from award-winning Southern fiction author Michelle Shocklee.

1944. Maebelle Willett arrives in Oak Ridge, Tennessee, eager to begin her new government job and send money home to her impoverished family. She knows little about the work she will be doing, but she’s told it will help America win the war. Not all is what it seems, however. Though Oak Ridge employees are forbidden from discussing their jobs, Mae’s roommate begins sharing disturbing information, then disappears without a trace. Mae desperately attempts to find her but instead comes face-to-face with a life-altering revelation―one that comes at significant cost.

1979. Laurel Willett is a graduate student in Boston when she learns about the history of Oak Ridge, Tennessee, where thousands unknowingly worked on the atomic bomb. Intrigued because she knows her Aunt Mae was employed there, Laurel decides to spend the summer with her aunt, hoping to add a family connection to her thesis research. But Mae adamantly refuses to talk about her time in the Secret City. Mae’s friends, however, offer to share their experiences, propelling Laurel on her path to uncovering the truth about a missing woman. As Laurel works to put the pieces together, the hidden pain and guilt Mae has tried so hard to bury comes to light...with potentially disastrous consequences.
