Blood Zombie

Cain must get across the United States to be with his fiancée, Sara. Their jobs had them a continent apart when the zombie apocalypse began.
He steals a hotdog-shaped-lunch-truck to make the cross-country journey. He sleeps in it. He cooks it in. He is safe in it.
Days have passed since the phones stopped working. Last he knew Sara was safe at a mansion, built like a medieval castle. Only blind faith tells him Sara is still alive.
Along the way he comes across a hapless, desperate, young woman and brings her with him. She is the first in a series of survivors joining him on his long journey. He struggles with being the impromptu leader of the small group. He does not want to care about these people, just wants to get to Sara.
Cain must resist the temptations of the desperate young woman. Must resist deserting the survivors who infuriate him. Must find weapons. Must find gas. Must find food. Must survive.
