The Singularity is Closer than it Appears
A Singularity Novel

Avogadro Corp: The Singularity is Closer than it Appears is a techno-thriller that explores how artificial intelligence will emerge and how humanity will respond to it.

When the ELOPe project is threatened to be cancelled because of server shortages, David makes a subtle change to the software allowing it to secretly modify company emails to ensure the success of the project.

But soon ELOPe is social engineering people around the company to get more servers allocated to it, to modify other software to expand its own capabilities, and to neutralize threats. As David and his coworkers slowly realize what’s happening, they take ever escalating actions to shut ELOPe down, only to find the software is always one step ahead of them.

A Singularity Novel

Leon Tsarev is a high school student set on getting into a great college program, until his uncle, a member of the Russian mob, coerces him into developing a new computer virus for the mob’s botnet – the slave army of computers they used to commit digital crimes.

The evolutionary virus Leon creates, based on biological principles, is successful — a little too successful. All the world’s computers are infected. Everything from cars to payment systems and, of course, computers and smart phones stop functioning, and with them go essential functions including emergency services, transportation, and the food supply. Billions of people may die.

But evolution never stops. The virus continues to change, developing intelligence, communication, and finally an entire civilization of A.I. called the Phage. Some may be friendly to humans, but others most definitely are not.

Leon and his companions must race against time and the military to find a way to either befriend or eliminate the Phage and restore the world’s computer infrastructure.

Hertling_TheLastFirewall_EbookTHE LAST FIREWALL
A Singularity Novel

In the year 2035, robots, artificial intelligences, and neural implants have become commonplace. The Institute for Ethics keeps the peace, using social reputation to ensure that robots and humans don’t harm society or each other. But a powerful AI named Adam has found a way around the restrictions.

Catherine Matthews, nineteen years old, has a unique gift: the ability to manipulate the net with her neural implant. Yanked out of her perfectly ordinary life, Catherine becomes the last firewall standing between Adam and his quest for world domination.

Hertling_TheTuringException_EbookTHE TURING EXCEPTION
A Singularity Novel

The year is 2045, and a nanotech disaster is halted in the nick of time, but only by nuking Miami. No one knows whether it was an accident or terrorist incident. Since only AI have the intellectual capacity to create self-replicating nanotech, the blame for the disaster falls on all of AI-kind. AI are outlawed in the United States, and subject to tough new restrictions around the rest of the world, and those with neural implants that augment their cognitive abilities are now viewed with suspicion.

XOR, a collective of AI who believe the world has room for humans or AI but not both, rapidly increases in power and influence.

Catherine Matthews, who ten years earlier saved the world from a rogue AI with her unique power over the net, is living in exile on a remote island with the two inventors of AI, Mike Williams, and her husband, Leon Tsarev. They alone see the true threat of XOR. But they no longer have the government backing they once possessed. Now their small band must work together to stop XOR and save the human race.

Available March 26th, 2015.



“A tremendous book that every single person needs to read. In the vein of Daniel Suarez’s Daemon and Freedom(TM), William’s book shows that science fiction is becoming science fact. Avogadro Corp describes issues, in solid technical detail, that we are dealing with today that will impact us by 2015, if not sooner. Not enough people have read these books. It’s a problem for them, but not for the [emergent] machines.” – Brad Feld, managing director Foundry Group, cofounder TechStars

“I found myself reading with a sense of awe, and read it way too late into the night.” – Gene Kim, author of Visible Ops and The Phoenix Project

“A terrific, and stunningly believable, account of how the first sentient artificial intelligence might accidently arise.” – Jeff Weiss, senior web architect

“Avogadro Corp is a fascinating look at how simple and benign advancements in technology could lead to the surprise arrival of the first AI. And like all good techno-thrillers, the reality of AI is less than ideal.” – Jason Glaspey, founder,,

“This is a highly entertaining, gripping, thought inspiring book. Don’t start without the time to finish — it won’t let you go.” – Gifford Pinchot III, founder Bainbridge Graduate Institute, author of The Intelligent Organization

“HAL, the self aware CPU from 2001 a Space Odyssey, is a kitten compared to ELOPe.” – Shawn Chesser, author of Trudge and Soldier On (Surviving the Zombie Apocalypse series)
