Bright New Dawn!
But the trouble with Bright New Dawns is that they're usually followed by cloudy days. With scattered showers. Life Outside the Store is much colder than the four-inch-tall nomes expected. And there aren't any walls . . . it's all very unsettling.
Still, the nomes are finally adjusting to their new home at the abandoned quarry, when a Sign arrives announcing the quarry is to be reopened. The humans are coming to mess things up (as usual), but this time the nomes might just fight back -- if they can find a way to rouse the mysterious Dragon in the Hill.
