The Promised Paradise

Thirteen doesn't know the ways of the outside world. All she's ever known are the walls of her containment cell, and the three other children that live with her in it. But when a new child comes into the cell with them, with stories of the outside world, they are filled with hope. They work together and put aside their differences, and escape the wretched place. However, it seems that the outside world is much more brutal and horrible than they expected, and they find that living in a containment prison cell, is better, than dying in hell.
