Ash American Fallout Ash in El Dorado Paperback

Ellena Reed has found safety in a Rocky Mountain nuclear bunker. Six months later, air is running out, and she has no choice but to join a small group of refugees traveling to a mythical "billionaire's bunker" sixty miles to the south.

But the Yellowstone eruption has transformed the landscape into a desolate volcanic wasteland. And the group isn't alone: some animals survived the blasts, and they aren't all human.
