Haven Terra is still recovering from an internship that brought her literally to the brink of hell when a trip to New Orleans leads to more trouble. There, while taking part in a student volunteer program, Haven and her friends Dante and Lance run across an enclave of devils known as the Krewe. These shape-shifting devils are more reckless and vicious than any Haven, Lance, and Dante have encountered.
Yet the friends soon discover that their French Quarter housemates are also angels in training, and together they must face off with the Krewe in their quest for wings. But Haven's resolve is tested when Lucian, the repentant devil with whom she was infatuated, resurfaces and asks her for help escaping the underworld. Can he be trusted? Or will aiding him cost Haven her angel wings and her life?
