Bella is a pure white flower and the red represents Edward showing that he has left a permanent mark on her
another idea is that Bella is the flower and part of her left when Edward left so the petal falling off kinda symbolizes that
all of the pics have something red in it to represent blood because it is about vampires. lol
Nothing at all
Edward is looking into the distance, while Jacob is protecting belle from edward.
The cat on the front cover of "Sign of the Moon" is Stoneteller (Teller of Pointed Stones).
The flower losing its petal represents Bella losing a drop of blood
the moon
Google satellites are closer to the Earth than the NASA satellites are to the moon. And those pictures are pretty good.
New Moon
More like New Moon (empty hole in space) but with light around a dark circle
it represent the color of the moon
New Moon, the stem of the flower is green
It is a ruffled tulip and Stephenie Meyer didn't have anything to do with creating this cover so on her website StephenieMeyer.com she states that even she doesn't know what it means.
