The past meets the future in Book Four of the Code Word series.
The EMP blast set off twenty years ago, at the end of Book Three, foiled plans for mass extermination but divided the country. Everything west of the Rockies had its power grid destroyed and has become a Wild West, governed by the Organites, while east of the Mississippi is still tightly controlled by the ubiquitous AI system Apex and is racing ever more quickly into the future. The area in between is left as a hotly contested, lawless war zone.
Adam, a restless twenty-year-old roaming the country with his parents, Shawn and Destiny, finds an antiquated communications device and makes contact with a young woman, Joan, from Apex’s side. The two will develop a profound bond, even as their two worlds clash.
When it is discovered that an enemy far greater than Apex is threatening the entire planet, our heroes are sent on a desperate chase to reboot an archaic defense system before catastrophe hits. Humans and AI have very different ways of assessing their risk of total extinction, so instead of cooperating with each other, the war for survival intensifies, while Adam and Joan find themselves on opposite sides of the battlefield.
But unbeknownst to Adam, Joan has a secret that could destroy their relationship . . . and change the course of human history.

Alex Schuler

Alex Schuler began his career as a Navy pilot, then developed AI software for the commercial and defense sectors. His systems have been deployed on Navy ships and submarines, as well as NASA space shuttles. Alex turned to writing exciting and accessible science-based fiction to explore the ethical and philosophical implications of the technology he helped develop. His characters question their place and purpose in a rapidly changing world of ever-more-sophisticated—and potentially dangerous—technological advances. 

Code Word Access, the first novel in Alex Schuler's Code Word series, shot to #1 on Amazon in the sci-fi category.

An early fan of Star Trek (the original, of course), The Outer Limits, and Sigourney Weaver in the Alien movies, you might find Alex wandering the halls of ComicCon or reading a great sci-fi book under redwood trees. Which book? Maybe Dune (Frank Herbert) or Stranger in a Strange Land (Robert Heinlein).
