Z-Day Series by Daniel Humphreys

Eight years after Z-Day, the surviving remnants of mankind face the unknown. The fences and walls kept the ravenous undead at bay until they wasted away. A once overwhelming foe has turned feeble and weak, and a world gone wild seems ripe for reclamation. The scars of the long war run deep. And hope is a dangerous thing when the real enemy might just be the survivors themselves. "A Place Outside The Wild" is a full-length, self-contained novel 626 pages in length.
