When Seraphina was younger, she healed her best friend's injured hand. Terrified by the inexplicable cure, the girl shunned her. From that day on, Seraphina found herself without friends, a freak and an oddity. And so she obeyed her mother’s rule to refrain from using her innate ability, heeded her mother's warning that its use could land her in the local mental health facility alongside her aunt and grandmother.
But when sixteen-year-old Seraphina finds a mysterious, wounded boy hiding in the hollow in the woods behind her house, she can't hold out against the overpowering urge to help him. She is drawn to him each night, and as they come to know one another, their irresistible attraction blooms.
She longs to uncover his secrets — where he comes from and why he's hiding and how he came to be so wounded — and to share her own, though she knows it's forbidden. And while her healing touch seems to be helping him, it's hurting her. When the symptoms of psychosis — experienced by the women in her bloodline who used their powers — begin to plague Seraphina, she is faced with the unbearable choice of saving her sanity or the boy she’s come to love.
