William Hertling is the author of the award-winning Avogadro Corp: The Singularity Is Closer Than It Appears, A.I. Apocalypse, and The Last Firewall. His near-term science-fiction novels about realistic ways strong AI might emerge have been called "frighteningly plausible", "tremendous", and "must read".

He's been influenced by writers such as William Gibson, Charles Stross, Cory Doctorow, and Walter Jon Williams.

William Hertling was born in Brooklyn, New York. He grew up a digital native in the early days of bulletin board systems. His first experiences with net culture occurred when he wired seven phone lines into the back of his Apple //e, creating an online chat system.

He currently resides in Portland, Oregon. By day he works on web and social media for HP. Follow him on twitter at @hertling or visit his blog williamhertling.com.

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 -- 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 may die.

But evolution never stops. The virus continues to evolve, developing intelligence, communication, and finally an entire civilization.

Some may be friendly to humans, but others are not.

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