Okay then... hmm.. what about.. this~
Earth is in ruins, it can no longer support life. So humans have left it for a different planet. But some kids are left behind. These kids are not ordanary. They have powers. They must find a way to live on the broken Earth untill the space ship comes back to rescue them.. but what they don't know.. is that the ship has crashed, and will never come back.
Or this~
Humans have left Earth in search of a new planet. They are trying to get to one that can support life. Suddenly, they are hit by... something and crash land on a distent planet. Only some kids and teens, and one adult, live. They find that this planet is a bit like earth... but stange things are happening on this planet....
