The Fall of Five is the fourth novel in the New York Times bestselling I Am Number Four series by Pittacus Lore. The Garde are finally reunited, but do they have what it takes to win the war against the Mogadorians?

John Smith - Number Four - thought that things would change once the Garde found one another. But he was wrong. After facing off with the Mogadorian ruler and almost being annihilated, the Garde know they are drastically unprepared. Now they're hiding out in Nine's Chicago penthouse, trying to figure out their next move.

The six of them are powerful, but they're not strong enough yet to take on an entire army - even with the return of an old ally. To defeat their enemy, the Garde must master their Legacies and learn to work together as a team. More important, they'll have to discover the truth about the Elders and their plan for the Loric survivors.

And when the Garde receive a sign from Number Five - a crop circle in the shape of a Lorien symbol - they know they are close to being reunited. But could it be a trap? Time is running out, and the only thing they know for certain is that they have to get to Five before it's too late.
