Short Synopsis
Rich Restucci presents Book 4 in the Zombie Theories series.

Full Synopsis
Immunity. It means a lot to those without it.

Sanctuary does too . . .

Traveling across the country, an arrogant, rude, and ironically immune man's group runs from a government hell bent on stealing his immunity. With millions dead and some of the infected getting smarter, it's all-out war.

When Alcatraz, one of the last bastions of civilization in the United States, comes under attack, some will emerge victorious, and some will emerge infected. Both sets of survivors of the worst plague in history must come together to fend off hordes of the undead and those not dead but no longer human.
