At two o'clock in the afternoon on July 27, the city fell within twenty minutes.
Lu Yuan, a construction engineer, survived for twenty-one days during the zombie apocalypse before dying in a horde.
Then he woke up.
July 26, 6:45 a.m. The day before the apocalypse began.
The memories of those twenty-one days are etched into his mind: the zombies on every street, the structural weaknesses of every building, and the time and place each companion died. He doesn't know why he has returned, or whether this is his last chance.
He has less than thirty-two hours.
He contacted a truck ahead of time, stockpiled thirty barrels of water and ten boxes of canned food, and chose as his shelter a building whose construction plans he had reviewed. He knows every load-bearing column and every fire escape better than anyone. This time, he won't sit back and wait to die.
But the apocalypse is never just one person's apocalypse.
Will the fate he fought so hard to change be waiting for him at another crossroads? Can he really save the people who died before his eyes this time?
And the people he has yet to meet: the surgeon trapped on the sixth floor of a hospital for twenty days, the woman who survived alone atop a thirty-meter water tower for ninety-nine days. Their stories are only just beginning.
Fix that window. Fix everything that can be fixed.
