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.
