The Orbital Corporations now control the world. In the ruins of an America ravaged by the Rock War, ex-fighter pilot Cowboy, who can be "hardwired" via skull sockets directly to his ride, has become a panzerboy, a hi-tech smuggler riding armored hovertanks through the balkanized countryside. He teams up with Sarah, another tough-as-nails gun-for-hire, to make a last stab at independence from the rapacious Orbitals. They gather an unlikely gang of misfits for a ride that will take them to the edge of the atmosphere.

Solip:System begins shortly before the ending of Hardwired and continues beyond that point. In Solip:System, the main character is the computer personality Reno (a minor character in Hardwired). The author intended that this book would provide a link between Hardwired and Voice of the Whirlwind.

Etienne Steward is a clone, also known as a beta. When he awakes, his memories are fifteen years old, because the original Steward—the alpha—never bothered to have his memories updated. In those fifteen years, the entire world has changed. An alien race known as The Powers has established relations with humanity. The Orbital Policorp which held his allegiance has collapsed. He fought and survived the off-world Artifacts War, but dozens of his friends did not. Both his first and second wives have divorced him. More importantly, someone has murdered him, causing the activation of the beta back-up. Now Steward has to figure out who wanted him dead, if he doesn't want to die again.
