For a post-apocalyptic zombie novel that is set after the zombies have won and humanity isn’t just trying to survive but salvage some kind of lower existence, Tankbread would seem to present a story with nowhere left to go but into a bleak future; humanity has no existence left to fill except to serve the upper class, now comprised of zombies that have managed to sustain themselves and elevate their intelligence to near full capacity by feeding regularly on human stem cells. In this vein, Tankbread presents an interesting comment on class in our present, not-yet-apocalyptic society.
The story begins with a courier that remains unnamed throughout. He is being patronized by an evol, one of the upper class of zombies that is intelligent enough to lead. The courier’s charge is to go to the Sydney Opera House, where some of the last of humanity have set up a protected community, and pick up a package. There we learn the secrets of Tankbread and the morally questionable pact humanity has made with the evols for survival. Essentially, Tankbread are human clones the surviving humans create to feed the evols in exchange for an agreement that they will leave the humans in the protected communities alone. As the courier is learning all of this, feeling safe in this Australian landmark, the Opera House is attacked, but the courier escapes with a Tankbread he later names Else and a charge to get her to a research facility across the country.
