ELI5: Explain Like I'm 5

The 100 (novel series)

The 100 is a book series about a group of people who live in space because the Earth isn't safe for them anymore. They all come from different parts of the space station and have different jobs, like doctors and engineers.

One day, the people in charge of the space station decide to send 100 teenagers down to Earth to see if it's safe for humans to live there again. The teenagers are chosen because they've broken the rules and are being punished.

When they get to Earth, they find that it's not what they expected. The air is breathable, but there are dangerous animals and plants. And they're not alone - there are other people on Earth, some of whom are not happy about the newcomers.

The story follows the 100 as they try to survive on Earth and figure out what's really going on. They face many challenges, from fighting off dangerous animals to dealing with unexpected alliances with other groups of people. And they learn that things are not always as simple as they seem, and that sometimes the people you thought were your enemies are actually your friends.
