If you hadn't noticed, THE SEVENTH BOOK TITLE AND COVER HAVE BEEN REVEALED RECENTLY!!! I would have responded earlier, but I was off writing my fanfic (which I have to hurry up and finish so I can get the final chapter out before United As One is released in June). And if you didn't notice this, the cover has another element on it:
Ice.
So what do you guys think it means? I assumed it had something to do with Marina, but we already have The Power of Six to represent her.
In I Am Number Four, the cover had what looked like Fire on it, which I realized represented John's Lumen. And after that, we had Water on the cover of The Power of Six, and I'm pretty sure that either represented Marina's name, meaning "of the sea," or maybe it connected to that lake where the final battle in TPO6 takes place. The Rise of Nine had what looked like Sand, and I immeidately thought it meant the desert in New Mexico. I'm not exactly sure, but I think that the element on The Fall of Five is Cobblestone, or just stone in general. It might represent the cell where Sam was kept prisoner, or the look of everything after John and Ella are in that vision. I didn't understand The Revenge of Seven's cover until after I read it, and released the Plant Life and Stone on the cover represented the Sanctuary and the jungle surrounding it. The Fate of Ten looked more like Concrete than ice, personally speaking. I assumed that was representing the streets of New York.
So, in the covers, if I was correct, we have: Fire, Water, Sand, Stone, Plant Life, Concrete, and finally, Ice.
The ice might represent Marina, but then again, they could've just had that as The Fall of Five or The Revenge of Seven cover. But let's think about it. Ice is a cold, stark element, usually associated with change. Or maybe it means death. Just guessing. Hope this means something.
