It is 2026 and humans have found a new planet that looks like Earth 5 years away.

As Earth is slowly dying the Government quickly sets up a space shuttle and takes 5,000 people to the planet to find out about it.

Once they are there they set up a base and explore part nearby parts of the world.

This is when they discover the Na'vi, or in English, The People.

They try to live together in peace but a rock that was like coal but burnt for longer and gave more energy and light was discovered and they began to dig it up.

However this angered the Na'vi as their forest was being destroyed and they fought to protect their forest.

Jake Sully had been brought in and led the Na'vi against his orgional species and it had worked- for ten years- but then Earth was going from bad to worse.

In Sarah's time, there was rules everywhere.

You would only get one meal per day because there was too many people on Earth.

You would have to go to a meal center and there would be people making sure you are all the food. If you didn't, you would face a fine, and no food for two- five days depending how many times you broke the rule.

You could not litter.

And many more rules. It would take a month to list all the most important ones.

In places where there was no room to grow things you would get a tablet to eat and it would have all the nutrients and stuff that you needed.

Sarah live a very poor life, she didn't have any money to pay for the expensive one meal a day and so has to steal to stay alive. However this makes her vulnerable to being caught and killed, and with her record of misbehaving she could be killed on the spot. Even though she's 15.
