A light conversation over coffee tosses the devil's daughter out of the frying pan of life's problems and into the fiery depths of hell. Sere Mal-Laurette was warned against meeting Jennifer, the real woman behind her doppelganger body. However, she didn't mention that instruction to Jennifer during their numerous psychically bonded moments. So when Jennifer shows up in front of Sere's apartment, the doppelganger doesn't see much choice other than to invite the housewife in for a cup of coffee. Before the day is out, Myles's sweet little dog has turned into a hellhound, Sere's friend and sidekick Fisher has succumbed to his demonic possession, and supersized crawfish have emerged from the swamp. Sere is forced to wonder if she should have heeded the warnings about Jennifer. But is the widening of the hell mouth a result of one morning's coffee conversation, or is something more sinister at work? Sere has plenty of other explanations to choose from. There are the lost souls of the damned that Marjory Laroque cast into hell in her attempt to raise a new devil. There's the fact that Sere's sweet angel and mother figure, Sanguine, has been imprisoned. Worst of all, Sere's very presence among the living could be the cause of the impending apocalypse. Once again she needs help curbing the chaos, but this time, she'll call on her support system in hell.
