Thirteen by H. Ferdosy

A discovered conspiracy. A ransom gone wrong. A two-month coma. Spoiled Iranian girl Neda awakes to find her parents dead—a tragic murder at the hands of her now-executed fiancé. But Neda saw the perpetrators, and he wasn’t one of them. The justice system dismisses her. Evidence mysteriously vanishes. And when others begin to die, she knows her own life could end just as brutally at any moment. All it will take is her enemies catching up—or her suicidal tendencies taking control. When her losses become all-consuming, there is one way forward: turn the tables and finally get revenge. When the only option is to kill or be killed, one thing is clear: this war will end in blood.
