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 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.
