Sadie Ritter is sixteen years old, nine months pregnant and scared out of her sweet nerdy mind. Having a baby that young is tough, but with the support of her loving family behind her, everything should be okay. Oh yeah - and also her baby is the Antichrist and it's going to break open the barriers between earthly and demonic planes and unleash eternal suffering to all of humankind. Plus there's a shady government organization and a Satanic cult both intent on kidnapping Sadie's baby for their own nefarious purposes. Other than that though... should be fine.
