A series of global earthquakes cascade across the world, their ferocity unmatched by any other natural disaster in human history. Cities are turned to rubble in moments, deep bunkers are sealed shut in an instant, tens of millions are dead in the first hours, and as aftershocks threaten to further destabilize what remains, those few who survived are forced to navigate a broken country.

On her Virginia homestead, Mara Padgett faces an impossible task: keeping her three children safe as food runs low and desperation runs high. Separated by hundreds of miles from his wife at their homestead, Logan barely survives a plane crash and takes a young orphan under his wing, but must soon choose between the child's welfare and quickly returning to his own family.

Meanwhile, Mara's sister Deb is one of the few to have survived the cataclysmic tremors triggered by the New Madrid fault line that left much of the East Coast in ruins. With nothing left for her in Memphis, she embarks on a perilous trek across the ruined landscape to join her sister in Virginia, though what she finds along the way will test her in ways she can never imagine.

In Washington, D.C., geologist Ripley Baxter is buried alive in the remains of the White House bunker, with the President presumed dead and no hope for rescue. She must summon the strength to free herself from the rubble or face a slow, agonizing death, but nothing has prepared her for the journey – and obstacles – she will face along the way.
