Satariel Grigori is a devil. No, he's THE Devil, and he wants to repent and return to his Father in Heaven. But can he? Is it even feasible? The answer may lie in one unconventional preacher at the verge of losing his church. And Satariel, known as "S" to those closest to him, has his work cut out for him in, convincing Thomas of his identity and convincing him to act as his advocate before GOD, all the while concealing his plans to defect from the other Grigori brother, those angels who fell with him long ago, who would most certainly take exception to this. Deadly exception. For while Satariel might have once been the highest angel, that does not presuppose him to be the most powerful. S's change of heart could spell his doom, as well as that of Reverend Abernathy and his family.
