The zombie apocalypse didn't begin on Z-Day—it's been raging in secret for 150 years. From an 1872 military unit's first walker encounter to Nazi experiments in concentration camps, from Cold War cover-ups to the final days before collapse, these classified stories reveal the conspiracy that doomed humanity. While the world slept, Unit 73 and AEGIS fought a shadow war against the walking dead. Some secrets should stay buried—but like the dead themselves, truth always rises.

The Walker Chronicles expands the universe of The Dying of the Light trilogy, uncovering the untold history of humanity's fight against the walking dead. While David Blake's journey in END, INTERVAL, and BEGINNING shows the apocalypse and its aftermath, these essential stories reveal the covert battles that raged for decades before Z-Day changed everything. Each tale deepens the conspiracy, heightens the horror, and illuminates the sacrifices made to keep humanity alive.
