Miller, fresh from too many pampered years at university, has managed to lose a PhD, a girlfriend, and her father's car. With parents now committed to a regime of find-your-own-way tough love, he's fallen off the fast track to success, and finds himself working in a shabby garden centre on the edge of nowhere. The staff are a collection of dropouts and oddballs, the boss is very shady, and Miller's not sure half the stuff they sell is legal.

Still, he's learning to get on with things and make do, finding a brand new path through life, but...an alien invasion disguised as a bright and shiny big-box store from out of town? That really isn't helping.

If Miller wants to protect his job and save the world, he's going to have to dig deep and get his hands dirty.
