Robin just wants to breathe. Even if she unseals her airtight mask and strips away her protective suit, a lungful of non-filtered, fresh, real air would mean death. But death won't be too uncommon for someone like her. She's a Courier, after all. When the virus hit, and the lockup took effect, the government enlisted its surplus of convicts as candidates for the most important job they would ever do in their lives. Delivery. Because the thousands of permanently isolated city-folk would need to survive somehow. Time is a Courier's precious currency: offering incremental reductions in often lifelong sentences. All they must do is finish their contract without someone else killing them for it first - and it isn't until Robin comes across an escort job worth 30 years, that she really begins to understand how badly her fellow convicts want their freedom. But this won't be a normal job.It isn't every day that she would haul a fresh criminal across to Seclusion - the mysterious detention centre near the edges of the city. And as much as Robin misses the old world, she doesn't miss her muddy past; especially when it begins catching up to her.
