Zombie Apocalypse Aftermath: The Night Sweeper - The Sweeper Saga, #1

It's 2105 and Cray has a killer life - literally.  He spends every night hunting zombies to keep everyone else in New York safe.  Of course he's alone, has a crap relationship with his father, and could die at any moment, but that's not so bad. Right?After all, thanks to his tireless efforts and the efforts of the other Night Sweepers, society has a fighting chance of recovering from the zombie apocalypse and being normal again.
Enter Jonathan Harbin, the son of the psychopath that made the virus that created the zombie horde.  Emerging from obscurity, he claims to have created a new strain that could decimate the remaining populace of the planet.  Suddenly everything Cray has fought for could be gone overnight.  There's only one solution:  Harbin has to go away.  To do this, he's going to have to join forces with the stunning Mira Winston, a government agent with dark secrets of her own.
Thus begins a dangerous infiltration that will lead him to terrifying revelations and the brink of death.  He will quickly learn his society is not what it seems, and that he's more connected to Harbin than he could ever have imagined.
