So, Nevermore, the final installment in the Maximum Ride series, comes out August 6, 2012.
Now, here's the thing: In 2007, when Saving The World And Other Extreme Sports (the third installment) was made, it said this would be the last book in the "trilogy". But then, in 2008, The Final Warning was made. Therefore, the Maximum Ride series hadn't drawn to a close. But i feel like this is it. This is the end of Maximum Ride.
Also, i think, that the title Nevermore is based off of Edgar Allen Poes The Raven, in which a raven says "Nevermore". Since they are 2% avian (bird) i would think that is what the title Nevermore is getting at.
Here is a book cover for Nevermore by James Patterson:
