Apocalypse

"In some strange way, I feel the diary is more important than me. I will go but these words and everything and everyone they represent, must not - cannot - disappear."

Jack Baldwin knows only too well what it's like to lose everything ... again and again and again.
In the months after a rogue comet destroyed the planet, killing 99% of the people on it, he lost his family, his friends and nearly his sanity.
Dragged back from the brink by the kinship of fellow survivors, they set about creating a new world from the ashes of the old. But danger lurks everywhere in the city, in the form of a larger, more heavily armed group of fellow survivors. They beat them once, but a rematch seems inevitable. And the enemy doesn't fight fair.
Can Jack and his crew find a way to survive and thrive until the darkness of the ash cloud lifts? How do they defend themselves against a fearsome force,hellbent on their resources and revenge?

And what's Plan B if they can't?
