We are not alone... more's the pity. Three poignant, sometimes blackly comic accounts, where unlikely heroes - kids, screw-ups, survivors - stumble their way through protecting Earth from faintly baffling alien invasions. It's one of the oldest devices in science fiction, from Wells' The War of the Worlds to Invasion of the Body Snatchers and The Thing. Why do so many aliens want to invade the Earth anyway? Who's going to stop them? Is this going to take long?
