Invader Zim (Invader Zim #46)

When ZIM and Dib receive the same Irken distress signal from the stormiest place on Earth-Pandora's Quadrangle-they both race to answer it. But the horrible surprise at the Quadrangle's core will lead them both (and GIR! Don't forget GIR!) to a far corner of the universe, and a world where neither of them are welcome. Part one of a four-part story!
