When a rogue Mogadorian meets up with a mysterious amnesiac in Santa Monica, he knows that there's more to this guy than meets the eye. In fact, he might just hold the key to everything.

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.

The year is 3589, fifteen hundred years after Commonwealth forces barely staved off human extinction in a war against the alien Prime. Now, an even greater danger has surfaced: a threat to the existence of the universe itself.

At the very heart of the galaxy is the Void, a self-contained microuniverse that cannot be breached, cannot be destroyed, and cannot be stopped as it steadily expands in all directions, consuming everything in its path: planets, stars, civilizations. The Void has existed for untold millions of years. Even the oldest and most technologically advanced of the galaxy’s sentient races, the Raiel, do not know its origin, its makers, or its purpose.

But then Inigo, an astrophysicist studying the Void, begins dreaming of human beings who live within it. Inigo’s dreams reveal a world in which thoughts become actions and dreams become reality. Inside the Void, Inigo sees paradise. Thanks to the gaiafield, a neural entanglement wired into most humans, Inigo’s dreams are shared by hundreds of millions–and a religion, the Living Dream, is born, with Inigo as its prophet. But then he vanishes.

Suddenly there is a new wave of dreams. Dreams broadcast by an unknown Second Dreamer serve as the inspiration for a massive Pilgrimage into the Void. But there is a chance that by attempting to enter the Void, the pilgrims will trigger a catastrophic expansion, an accelerated devourment phase that will swallow up thousands of worlds.

And thus begins a desperate race to find Inigo and the mysterious Second Dreamer. Some seek to prevent the Pilgrimage; others to speed its progress–while within the Void, a supreme entity has turned its gaze, for the first time, outward.
