A poignant, lyrical debut novel about twins who navigate first love, their Jewish identity, and shocking results from a genetic test that determines their fate—whether they inherited their mother’s Huntington’s disease.

Eighteen-year-old twins Adina and Tovah have little in common besides their ambitious nature. Viola prodigy Adina yearns to become a soloist—and to convince her music teacher he wants her the way she wants him. Overachiever Tovah awaits her acceptance to Johns Hopkins, the first step on her path toward med school and a career as a surgeon.

But one thing could wreck their carefully planned futures: a genetic test for Huntington’s, a rare degenerative disease that slowly steals control of the body and mind. It’s turned their Israeli mother into a near stranger and fractured the sisters’ own bond in ways they’ll never admit. While Tovah finds comfort in their Jewish religion, Adina rebels against its rules.

When the results come in, one twin tests negative for Huntington’s. The other tests positive.

These opposite outcomes push them farther apart as they wrestle with guilt, betrayal, and the unexpected thrill of first love. How can they repair their relationship, and is it even worth saving?

From debut author Rachel Lynn Solomon comes a luminous, heartbreaking tale of life, death, and the fragile bond between sisters.
