Incursion (Paperback) (ISBN-13: 9798186834038)

A machine opened the door. A government decided where to aim it. Dr. Grace Thurston became the price.

Security consultant William Thurston arrives at Site Acheron to investigate a failure inside a classified mountain facility. His wife, Dr. Grace Thurston, is trapped in the medical wing when an impossible breach begins rewriting corridors, erasing records, and turning the hospital into a living maze.

As quarantine seals the surrounding town and military command prepares to weaponize the catastrophe against the city of Kheran, William and Grace face an impossible choice: save the person they love, or stop a machine capable of condemning thousands.

In a world of redacted files, impossible doors, and weaponized science, every number has a name. Incursion begins The Aperture Cycle, an adult science-fiction horror thriller about survival, memory, marriage, and the moral cost of turning the unknown into a weapon.
