Nuclear Armageddon... The world in radioactive ruins...

 So what?  

PHOENIX

The post-nuclear action-adventure classic that predicted coronavirus and defined a genre.

Now with a new introduction by Grady Hendrix.

A biologically engineered supervirus that turns humans into blood-thirsty geeks called Contams. Pitted against them, and the Dark Messiah who created them, is Phoenix, the only known Immune on the planet.

This complete Phoenix series: books one through five from Dark Messiah to Reap the Whirlwind.
