You know we're out there, living among you. You know we're waiting for our day to come. You have seen the power of our legacies. You know this is why they hunt us. You may think you know our stories. You are wrong. We each have our own story. We know the time has come to share them with you. Our legacies are your only hope.

It has been over a year since the invasion of Earth was thwarted in Pittacus Lore's United as One. But in order to win, our alien allies known as the Garde unleashed their Loric energy that spread throughout the globe. Now human teenagers have begun to develop incredible powers of their own, known as Legacies. To help these incredible and potentially dangerous individuals - and put the world at ease - the Garde have created an academy where they can train this new generation to control their powers.

Teens across the globe have developed incredible powers known as Legacies. Although they were meant to use these abilities to help the world, dark forces have been working against them from the shadows. Six and Sam Goode used to be part of a covert group that investigated suspicious incidents surrounding these Human Garde. Then they discovered they could no longer trust who they were working for and quit. But they’ll still do whatever it takes to protect these teens.

After the first wave, only darkness remains. After the second, only the lucky escape. And after the third, only the unlucky survive. After the fourth wave, only one rule applies: Trust no one. Now, it's the dawn of the fifth wave, and on a lonely stretch of highway, Cassie runs from Them. The beings who only look human, who roam the countryside killing anyone they see. Who have scattered Earth's last survivors. To stay alone is to stay alive, Cassie believes, until she meets Evan Walker.

Pittacus Lore finished telling the story of the Lorien Nine in the New York Times best-selling I Am Number Four and Lorien Legacies Reborn series. Now he’s back to recount an all-new adventure rooted in the real mysteries surrounding Roswell, New Mexico, that will enthrall fans of Brandon Sanderson, Jay Kristoff, and Amie Kaufman.
