While some people believe that there are only humans in the world, Maddie and Lexi believe there is more to it. While at a funeral, after a death of a fallen classmate, Lexi and Maddie reach the end of the cemetery.
Not because they wanted to, but because something was chasing them. When they do reach the end, which is blocked by a five foot black gate, they have no choice but to climb it.
When they do they find something beyond imagination, a whole academy hidden behind what seems to be a small forest. Considered to be students they look around, finding out that what they thought was true.
They are not alone in the world, and they are about to find out how many others are there.
Everyone has a basic normal life, you never think the unthinkable can happen, until it does. The apocalypse. Floods, Fires, tornados, all terrible scary things happening, and then sickness. Will this group of friends survive this?
