In 2460, eighteen-year-old Liv Newman dreams of a future beyond her lower-class life in the Metro. As a Proxy, she uses the neurochip in her brain to sell memories to wealthy clients. Maybe a few illegally, but money equals freedom. So when a customer offers her a ludicrous sum to go on an assignment in no-man's-land, Liv accepts. Now she just has to survive.

Rookie Forceman Adrian Rao believes in order over all. After discovering that a renegade Proxy's shady dealings are messing with citizens' brain chemistry, he vows to extinguish the threat. But when he tracks Liv down, there's one problem: her memories are gone. Can Adrian bring himself to condemn her for crimes she doesn't remember?

As Liv and Adrian navigate the world beyond the Metro and their growing feelings for one another, they grapple with who they are, who they could be, and whether another way of living is possible.
