In a world wrecked by climate change, in a society owned by the ultra-rich, in a city hollowed out by industrial flight, Hubert, Etc, Seth and Natalie have nowhere else to be. Now that anyone can design the necessities from a computer, there is little reason to toil within the system. The three of them turn their back on the world of rules, jobs, the morning commute and...walkaway. The walkaways discover the one thing the ultra-rich have never been able to buy: how to beat death. And now it's war – a war that will turn the world upside down.
