In I Am Number Four: The Lost Files #4, discover what has happened to one of the people with information crucial to the Garde coming together to fight to save Lorien—and Earth.

In this heart-racing 144-page companion novella to the New York Times bestselling I Am Number Four series, discover what happened to Malcolm Goode—the one human on Earth who can help the Garde learn the truth about their past and help them save our planet.

No one has seen Sam Goode's father, Malcolm, since he mysteriously disappeared years ago. Sam had always fantasized that he was abducted by aliens. But that was before he knew the truth: aliens do exist, and some of them seek to destroy our world. That was before he himself became another one of their captives.

Now father and son are both missing. . . . But when a rogue Mogadorian named Adam, who now has Number One's memories, decides the only way to make up for his past atrocities is to return home and infiltrate the Mogadorian stronghold, he'll find the key to saving both Sam and Malcolm's life.

A New York Times bestseller! Red Queen meets The Hunger Games in this epic novel about what happens when a senator’s daughter is summoned to the galactic court as a hostage, but she’s really the galaxy’s most dangerous weapon in disguise.

A Diabolic is ruthless. A Diabolic is powerful. A Diabolic has a single task: Kill in order to protect the person you’ve been created for.

Nemesis is a Diabolic, a humanoid teenager created to protect a galactic senator’s daughter, Sidonia. The two have grown up side by side, but are in no way sisters. Nemesis is expected to give her life for Sidonia, and she would do so gladly. She would also take as many lives as necessary to keep Sidonia safe.

When the power-mad Emperor learns Sidonia’s father is participating in a rebellion, he summons Sidonia to the Galactic court. She is to serve as a hostage. Now, there is only one way for Nemesis to protect Sidonia. She must become her. Nemesis travels to the court disguised as Sidonia—a killing machine masquerading in a world of corrupt politicians and two-faced senators’ children.

It’s a nest of vipers with threats on every side, but Nemesis must keep her true abilities a secret or risk everything. As the Empire begins to fracture and rebellion looms closer, Nemesis learns there is something more to her than just deadly force. She finds a humanity truer than what she encounters from most humans. Amidst all the danger, action, and intrigue, her humanity just might be the thing that saves her life—and the empire.
