After I Am Number Four came Generation One . . .

It's a year since John Smith and the Lorien Garde helped defeat the Mogadorian invasion of Earth.

Now all over the planet teenagers are developing new powers - new Legacies.

But this terrifies everyone else. Those with Legacies are forced to register themselves. They are cast out of families. Hunted. Some are murdered.

So the Garde create an Academy. A place where the gifted may come and learn. They will be trained to use their powers to help protect humankind.

But some believe there's a better use of their talents. They have other plans. And they don't care who dies to bring them about . . .
