A fateful summer of secrets and lies alters the trajectory of a young girl’s life in this glimmering debut about love, addiction, and the power of storytelling.

I’d been raised on secrets, I knew they weren’t a good idea.

Sixteen and living in a small Michigan town, Gertie is harboring a secret heavy enough to fracture her closest friendship. She and Cindy have been bonded since birth by the fact their fathers are addicts, but their unsteady home lives are a little easier when they’re together, sprawled on trampoline vinyl with pilfered vodka and dreams of moving to New York.

Everything was changing so fast. I didn’t know what was real.

After an accident involving a bonfire and an aerosol can sends Gertie to the hospital, she finds herself with nowhere to go but to Sioux Falls to live with her newly clean father. She sees it as a chance to escape the hometown drama she's caused, but it finds her all the same: parties without curfews, boys without boundaries, a compromising photo, tragedy back home . . . and her father, once again teetering on the edge of oblivion. Terrified of the consequences of being honest with Cindy, her sole refuge is the fantasy novel she’s writing, a portal to another world and the story of a young girl roaming a strange land, trusting her wits to survive.

I had to become a different person before I’d even figured out who I was in the first place.

Years later, when ghosts of the past surface, Gertie decides to write again about that explosive summer from the stabler shores of adulthood. Powered by the fierce imagination of her youth, Gertie finally allows herself the grace to tell a version of her story that she always hoped would be true.

Written with the feel and power of a ticking time bomb, Atomic Hearts is an unforgettable story of the relationships that shape us beyond all reason and the ways it might be possible to pull ourselves back from the brink.
