Fire Break

"Sam Hyatt and his family and students begin to learn more about the grim truths of living after the Rupture has changed physics and precipitated disaster across Earth. In a wrecked Colorado, Sam must lead the ones he loves in an effort to salvage what can be salvaged, and build anew what can be built. But, as Father Markus, trapped in a collapsing Denver, knows to his sorrow, this new world's rising warlords have other plans, and those don't include anybody else building anything that doesn't serve those new rulers. Can Sam and the people of Lyons manage to save enough from the old world, and adapt it to the new, that they can survive?" (source: Amazon.com)
