Zombie Apocalypse Series by Jack Hamlyn

An ordinary summer's day. The grass is green, the flowers are blooming. All is right with the world. Then the dead start rising. From cemetery and mortuary, funeral home and morgue, they flood into the streets until every town and city is infested with walking corpses, blank-eyed eating machines that exist to take down the living. The world is a graveyard. And when you have a family to protect, it's more than survival. It's war.

Necrophobia Book 2 Nightmare, New York. From Manhattan to the Bronx, Queens to Brooklyn, a hellzone of the walking dead, crazed survivalists, and deranged cults. One man will stand against them. One man will fight them street to street. He'll do anything to find his friends and his son. There's no pit he won't crawl through. No enemy he will not face. And God help anyone who gets in his way.
