The beautiful young photojournalist, Aileen O’Shannon, is not who she seems. For centuries, she has been a demon hunter, a sorceress who has tracked and killed small bands of demons that occasionally crossed into our world. But that changed when she joined Dr. Jack Oswald’s expedition to study one of hundreds of huge holes that mysteriously appeared overnight in the frozen tundra north of the Arctic Circle.
Instead of small sporadic incursions, hordes of demons now pour from these hell holes like water from a sieve. With bombing little more than a losing game of whack-a-mole, Earth’s armies are unable to destroy the portals. When Jack suggests a desperate plan, he is drafted to join Aileen and a team of other sorcerers and Army Rangers to travel to the demon homeworld. Once there, they will unleash a plague virus and set off a nuclear bomb to destroy the portal complex. It’s a suicide mission. But Aileen has given Jack’s wife her word to bring him back safely, and the demons have already killed three men under her protection. Just how far will Aileen go to avoid losing another?
