The First (fucked up) Generation.

The main character (Amber) and her friends are in a world like earth but things are different. Hybrid animals, weird plants and a lot of it is in ruins. Nobody knows how or why but the human race was wiped out and this was the first generation on earth for 2000 years. Everything was different.

The antagonist(Alistair(or is it?)) is kidnapping the first genoration of people to be back on earth to experiment on them. Nobody knows his intentions but when one girl escapes the experiments, information from the lab is leaked. He is not only doing experiments on kids but she noticed he was only kidnapping girls. Using them for his own pleasure as well as torturing them with experiments.

The weird thing is that over time things have changed DRASTICALLY. The main characters are noticing that they getting stronger, faster, and they can dp things that they couldn't do before.

The last generation left everything they would need to survive and more, in the bunkers that they were made in. The first generations designs are flawed. Some of the people got geneticly mutated with different animals, that alone has its flaws and its perks, giving them extra abilities. So a lot of the characters are flawed in the sense that they are not fully haman.

Where they live isn't in a civilization. It's just them in a little house that they made put of a base from 2000 years ago. Along with the other people its kind of like they each have a little tribe or maybe you could say their like a family.
