[1] The story is divided into two perspectives: one that follows a group of teenagers sent to a remote location for a retreat; the other focuses on a military base that has come into contact with monsters resembling demons.

The novel incorporates typical elements found within science fiction and blends it with the supernatural aspects of horror.

"[3] The senior pupils of St Peter's High School are on retreat to a secluded outdoor activity center, coming to terms with the murder of a fellow pupil through the means you would expect: counselling, contemplation, candid discussion and even prayer; not to mention booze, drugs, clandestine liaisons and as much partying as they can get away with.

Not so far away, the commanders of a top-secret military experiment, long-since spiraled out of control, fear they may have literally unleashed the forces of Hell.

Two very different worlds are on a collision course, and will clash in an earthly battle between science and the supernatural, philosophy and faith, civilization and savagery.
