Ever since her father was killed when she was just a child, Miranda Crabtree has kept her head down and her eyes up, ferrying contraband for a mad preacher and his declining band of followers to make ends meet and to protect an old witch and a secret child from harm. But dark forces are at work in the bayou, both human and supernatural, conspiring to disrupt the rhythms of Miranda's peculiar and precarious life. And when the preacher makes an unthinkable demand, it sets Miranda on a desperate, dangerous path, forcing her to consider what she is willing to sacrifice to keep her loved ones safe.
