Alex is a restless new agent who's spent her life being dragged down the path of least resistance and failing her way to the top. When she's assigned a new job with Dynamic National Technologies, Incorporated, she's promised an action-packed life of stopping crime, collaring evil Detractors, and committing espionage using cool guns and cool tech.

Inside the Settlement, a metropolitan enclave 20 by 20 miles square, everyone has an assigned role to play in working toward the ultimate survival of humanity, under the watchful eye of the Administrators. Outside the Wall, there is only a barren wasteland; a lifeless Earth destroyed by greed.

When DYNTEC sends Alex on a mission beyond the Wall to infiltrate a mysterious religious cult known as the "Kingdom of Heaven", what she finds there will challenge everything she believes to be true. Ultimately she will be forced to reexamine her loyalties, and choose between the Kingdom of Heaven and the kingdom of Earth.
