Living with other "mechs" since her wealthy parents transplanted her brain into a mechanical body to prevent her from dying in a horrible accident, Lia becomes a pawn in a religious leader's movement to outlaw "mech" technology and eradicate machines such as herself.

Lia, involved in an accident that should have killed her, wakes to find her wealthy parents have paid for her to have an experimental procedure that makes her a mech, one of a select group of people given mechanical bodies that never die or age, and though she tries to return to her old life, she finds nothing is the same, and is soon drawn into a group of mechs and begins to see the limitless possibilities of her new body.
