Famine [EPUB ebook] 

What happens when the richest nation on God’s Earth is driven to the outer limits of starvation? When the grain crop failed in Kansas it seemed like an isolated incident and no one took much notice. Except Ed Hardesty. Then the blight spread to California’s fruit harvest, and from there, like wildfire, throughout the nation. Suddenly America woke up to the fact that her food supplies were almost wiped out. Her grain reserves lethally polluted. And Botulism was multiplying at a horrifying rate.
