A thriller set in the bestselling AFTER post-apocalyptic world. When Mackie Dailey survives a cataclysmic solar storm that wipes out civilization and mutates others into violent killers, he seeks out the one person he cares about most. But when he returns to a college campus looking for Allie, he discovers she is a Zaphead—nearly unrecognizable as the human he once loved. Mackie becomes caught in a power struggle among a small group of survivors who turn the campus into a stronghold against the Zaphead threat. His old nemesis, Lucas Krider, has taken charge, but Krider’s vision of a new world is just as horrifying as the extinction they all face. Will Mackie sacrifice himself so the group has a chance to survive, or will his demons turn out to be more dangerous than the strange, rampaging creatures that nature has unleashed?

The second spinoff book in the bestselling AFTER post-apocalyptic series. After a devastating solar storm erases the world they knew, Mackie Dailey and a small group of survivors build a new life on a rural college campus. But there’s another kind of evolution threatening to wipe out the remnants of the human race: bizarre mutants known as “Zapheads” who destroy anything that moves. As the Zapheads adapt from mindless savages into more cunning predators, Mackie draws on his lethal skills as a former hit man to protect his new tribe. But Zapheads aren’t the only danger. Mackie’s old boss, Lucas Krider, is gunning for revenge with his own band of killers. As the campus becomes the battleground for the world’s future, Mackie discovers the biggest threat may be the monster raging inside him.
