Cut off from civilization and deep within insurgent-held territory, Walker and her team must team up with old enemies to defeat a merciless invasion force...a foe that's already mopping up their worldwide conquest. In the post-apocalyptic ruins of America, her prepper husband, Dixon, struggles to bug out of Judgment Day. None of Dixon's expensive preparations are enough in a world on the brink of annihilation. With nothing but his wits and the clothes on his back, Dixon must survive a cutthroat new-world order to save himself and his stepdaughter.
