The Return of Zim

Irk has perished.
Zim has fled, back to Earth, back to the squishy-skinned being he once called an enemy.
But what happens when Dib, or Devon, has just as many secrets as Zim? Just as bad a past?
Just an unstable of a future?
And what happens when that past comes back to haunt both of them, and they are unable to exorcise the demons of their own creating?
And what happens when Zim loses his cool, and alerts those who survived on Irk of his location, opening up the world to an Armada?
This and more in the series; The Return of Zim.

And now, will Zim be able to defeat his past?
Or will they both end up Burned in the end?
