It's 1954, and twenty-two-year-old Lucia Lafleur has always dreamed of following in her father’s footsteps. While sock hops and poodle skirts occupy her classmates, she dreams of bacteria and broken bones—and the day she’ll finally fix them.

After graduation, a letter arrives, and Lucia reads the words she’s labored a lifetime to earn—"we are pleased to offer you a position at the University of Pennsylvania School of Medicine." But in the midst of her triumph, her fiancé delivers a crushing ultimatum: forego medical school, or forego marriage. ​

With fractured hopes, she returns home to Louisiana, expecting nothing of the summer of '54 but sweet tea and gumbo while she agonizes over her impending choice. There, she unexpectedly befriends Nicholas, a dark-skinned poet whose dignity and intellect are a salve to her aching heart. Their bond, initially forged from a shared love of literature, soon blossoms into something as bewitching as it is forbidden. ​

Yet her predicament deepens when a trivial misunderstanding between a local white woman and a black man results in a brutal lynching, and the peril of love across the color lines becomes chillingly real. Now, fulfilling her lifelong dream means relinquishing her heart—and escaping Louisiana alive.
