The Sin Eater's Daughter

Seventeen-year-old Twylla lives in the castle, but although she's engaged to the prince, she isn't exactly a member of the court. She's the executioner. As the Goddess embodied, Twylla instantly kills anyone she touches. Each month, she's taken to the prison and forced to lay her hands on those accused of treason. No one will ever love a girl with murder in her veins--even the prince, whose royal blood supposedly makes him immune to Twylla's fatal touch, avoids her company.
