Marooned on an island, a group of alien young adults, saved from their fate of slavery, attempts reconstruct their shattered lives with a new one together on the sandy shores. Throughout all the dangers, however, with the lurking creatures in the darkness and the nameless fear of the shadows, there is one threat that may break everything apart: Their distrust of each other.

Zim is adjusting to his life among the humans at the dawn of the zombie apocalypse. His view of the corpses is pretty straightforward; they're dangerous and need to be destroyed. But when an unexpected encounter and an odd acquaintance leaves him clawing for answers, his view of the zombies changes. Now stuck between the two sides, he'll discover what it truly means to be 'human.'

When Dib contacts the spooky realm again, things, of course, go haywire. But instead of him being sucked in, something crawls OUT. Now, there are horrible things happening: Brutal murders committed by a phantom, storm clouds without rain, a monster in the dark. In order to save everything, Dib must team up with an unlikely partner. Can they save they've lost? Or will shadows win?
