The Wall's Backdoor Protocol

In the techno-thriller vein of Mark Russinovich, a border shooting between the partitioned nation of Torvold and the enclave of Lystra ignites a legal firestorm. When a defense contractor's secret protocol is exposed, a grieving family and a desperate one discover that the deadly flaw in the border wall's code was not a bug, but a feature—a backdoor left by lawmakers to serve the powerful, forcing them into a subterranean war for survival and truth.
