The 500

Elena woke up with nothing, no memories, no energy, no strength and no idea where she was.

All she knows is that she was taken from her life.
Her life that would of ended if it wasn't for the help of her skeptical saviors who rescued her from the hands of the unwelcome newcomers who invaded earth.
The only information they give her is that she cannot leave the facility, without facing certain death.

They plan on making an army out of those they saved from the Hands of evil, including Elena. But something is suspicious about her so called saviors.
And something is very off about Elena.

As Elena and her friends survive the strenuous training, they realized they are in for much more then they bargained for; And the idea that maybe the outside world is the only way to survive.

The hard truth burnt into their brain
There's thousands of them
And only 500 of us.
