The Fall of Five official description:
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 each other. They would stop running. They would fight the Mogadorians. And they would win.
But he was wrong. After facing off with the Mogadorian ruler and almost being annihilated, the Garde know they are drastically unprepared and hopelessly outgunned. 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 importantly, 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 Loric symbol—they know they are so 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.
The Garde may have lost battles, but they will not lose this war.
Lorien will rise again.
A number of prophecies were released on the official facebook page, giving an insight into what will happen to the main characters. It confirms the re-appearance of Sam Goode and suggests that he may be a narrator for The Fall of Five.
Sam Goode - We've taken too long and Bernie Kosar wasn't able to stop them. The second wave is upon us.
John Smith - It has only been a few hours, but already John's skin has taken on a pallor similar to Ella's. Dark circles forming around his eyes. It's almost as if he's being drained some how.
Sarah Hart - I hear Sarah scream. Her gun is making an empty clicking sound and, realsing that she's empty, the Mogs have started ascending on her. One of them reaches through the doorway and buries a dagger deep into her shoulder.
Number Six - "Do you think we're going to fight an entire army of Mogadorians without a few casualties?"
Marina - Something inside me snaps. I've never felt an anger like this before and it's almost comforting. The icy feeling of my legacy spreads through me, but it's different somehow, freezing and bitter and dead.
Number Eight - the beast swivels around and sinks its teeth into Eight's shoulders.
Number Nine - Bubbles break the surface of the swamp where Nine is still underwater. He's been pinned down there for almost a minute.
Ella - She's only just started getting her legacies. Who knows what she might be capable of.
Number Five - Burned into the crops with jagged precision is the Loric symbol for Five.
Malcolm - Sam is cradling Malcolm, who has a massive blaster wound in his midsection. His breathing is shallow and he's barely conscious; It doesn't look like he has long left.
Bernie Kosar- "BK went ot the roof to hold of the Mogs," Sam says. "He didn't come back."
Adam - If this Mogadorian defector is still alive, we're going to find him.
