If you've never heard of the Autumn series or David Moody I highly suggest you check out the website. Here is the description for the free ebook 'Autumn'
In less than twenty-four hours a vicious and virulent disease destroys almost all of the population. Billions are killed. Thousands die every second.
There are no symptoms and no warnings. Within moments of infection each victim suffers a violent and agonising death. Only a handful of survivors remain. By the end of the first day those survivors wish they were dead.
A small group of desperate people take shelter together in a village hall on the outskirts of a large city. Too afraid to venture out into the infected world, their shelter becomes a prison and the frightened group begins to splinter and crack under the emotional and physical pressure of the inexplicable situation.
Terrified and trapped without electricity, water or supplies, the survivors exist from hour to hour.
Then the disease strikes again. And all hell breaks loose.
