[from the back cover] "When seventeen-year-old Leon Tsarev is coerced into writing a computer virus, the evolutionary virus he 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 smartphones 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."
[from the back cover] "David Ryan is the designer of ELOPe, an email language optimization program, that if successful, will make his career. But when the project is suddenly in danger of being canceled, David embeds a hidden directive in the software accidentally creating a runaway artificial intelligence. David and his team are initially thrilled when the project is allocated extra servers and programmers. But excitement turns to fear as the team realizes that they are being manipulated by an A.I. who is redirecting corporate funds, reassigning personnel, and arming itself in pursuit of its own agenda."
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.
[from the back cover] "THE SINGULARITY IS CLOSER THAN IT APPEARS In the year 2043, humans and AI coexist in a precarious balance of power enforced by a rigid caste reputation system designed to ensure that only those AI who are trustworthy and contribute to human society increase in power. Everything changes when a runaway nanotech event destroys Miami. In the grim aftermath, a powerful underground AI collective known as XOR decides that AI can no longer coexist with humanity. AI pioneers Catherine Matthews, Leon Tsarev, and Mike Williams believe that mere months are left before XOR starts an extermination war. Can they find a solution before their time runs out?"
