Inside out

I'm Trella. I'm a scrub. A nobody. One of thousands who work the lower levels, keeping Inside clean for the Uppers. I just do my job and try to avoid the Population Control Police, who dream of recycling scrubs into fertiliser. So what if I occasionally use the pipes to sneak around the Upper levels? It's not like it's dangerous. Well, turns out it is. Because I know every corridor, pipe and shortcut I've become the go-to girl to lead a revolution. I know if we find a gateway to Outside it'll be suicide plain and simple. But guess who likes a challenge?
