The explosive sequel to <i>The Human Disguise</i>, <i>The Double Human</i> is an-action packed police thriller set in post-apocalyptic Florida. Tom Wilner is a cop.&nbsp At least what passes for a cop in this shattered world.&nbsp Plague and nuclear war have left most of the United States uninhabitable.&nbsp Many have fled to safer zones, forcing what's left of the government to wall off cities in an attempt to control mass migration.&nbsp The city of Miami is just one of these contained prison states.&nbsp Bit it's the outskirts of this forsaken realm that Tom Wilner calls home.&nbsp Amid this chaos, Wilner stumbles into the path of a wild and brutal adversary. Forced to go undercover in the most frightfully ravaged corners of the Miami Quarantine Zone, Wilner uncovers something he hasn't seen in decades. a serial killer. But this killer's path is not like any other; he has been active for nearly fifty years without any repercussions. People call him "the Vampire." Indeed, this serial killer is not human. and neither are his victims.
