We have waited generations for you…

Syd Chambers knows that there’s life on other planets because he’s descended from it. His father was from a distant world called Denza and has been missing–presumed dead–for years.

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

Syd Chambers grew up on Earth with his human mother and barely remembers his alien father from Denza, who left on a mission when Syd was very young. After leaving Earth, Syd learned the truth of his father’s disappearance on the planet Ashfall–his father had died protecting a devastating secret about the history between humans and Denzans.

Syd is now faced with a choice–free humanity from imprisonment on Earth, which will allow them to come into physical power beyond their wildest dreams; or destroy Earth so that humans never have a chance to enslave, torment, and kill other species again. It has been prophesied that Syd is destined to become a world-killer, but Syd is determined to choose his own fate, and knows there must be another path forward that will honor his father’s sacrifice.

This sequel to Pittacus Lore’s Generation One is the second book in an epic new series set in the world of the #1 New York Times bestselling I Am Number Four series.

Newcomers as well as fans of the original series will devour this fast-paced, action-packed sci-fi adventure that’s perfect for fans of Marvel’s X-Men, Alexandra Bracken’s Darkest Minds trilogy, and Tahereh Mafi’s Shatter Me series.

The Human Garde Academy was created in the aftermath of an alien invasion of Earth. It was meant to provide a safe haven for teens across the globe who were suddenly developing incredible powers known as Legacies.

Taylor Cook was one of the newest students and had no idea if she’d ever fit in. But when she was mysteriously abducted, her friends broke every rule in the book to save her. In the process, they uncovered a secret organization that was not only behind Taylor’s kidnapping but also the disappearance of numerous teens with abilities. An organization that has dark roots in the Loric’s past, untold resources, and potentially even a mole at their own school.

Now these friends, who have become known to other students as the “Fugitive Six,” must work together to bring this mysterious group to an end before they can hurt anyone else.

The first book in a pulse-pounding new series that’s set in the world of the #1 New York Times bestselling I Am Number Four series. The war may be over–but for the next generation, the battle has just begun!

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 and hopefully one day help mankind. But not everyone thinks that’s the best use of their talents. And the teens may need to use their Legacies sooner than they ever imagined.

Perfect for fans of Marvel’s X-Men and Rick Yancey’s The 5th Wave, this epic new series follows a diverse cast of teens as they struggle to hone their abilities and decide what, if anything, they should do with them. As a spin-off of the bestselling I Am Number Four series, those familiar with the original books and newcomers alike will devour this fast-paced, action-packed sci-fi adventure.

John Smith seems like an ordinary teenager, living a normal life with his guardian Henri in Paradise, Ohio. But for John, keeping a low profile is essential, because he is not an ordinary teenager. He’s an alien from the planet Lorien, and he’s on the run. A group of evil aliens from the planet Mogadore, who destroyed his world, are hunting anyone who escaped.

Nine Loric children were sent to Earth to live in hiding until they grew up and developed their Legacies, powers that would help them fight back–and help them save us. Three of them are now dead. John is Number Four, and he knows he’s next….
