Seventeen-year-old Serena isn't human. She is a bad blood, and in the city of Vendona, bad bloods are executed. In the last moments before she faces imminent death, a prison guard aids her escape and sparks a revolt. Back on the streets determined to destroy her kind, Serena is spared by a fellow bad blood named Daniel. His past tragedies are as equally mysterious as her connection to them. Unbeknownst to the two, this connection is the key to winning the election for bad bloods' rights to be seen as human again. But Serena is the only one who can secure Vendona's vote. Now, Daniel must unite with her before all hope is lost and bad bloods are eradicated, even if it means exposing secrets worse than death itself. United or not, a city will fight, rain will fall, and all will be threatened by star-crossed love and political corruption.
