The books are rearranged to spell "love." Another way to describe the books: Twilight- Bella discovers the night. (Edward) New Moon- The moon disappears in a new moon. (Edward leaves Forks) Eclipse- Bella chooses the moon (Edward) over the sun (Jacob) Breaking Dawn- Bella's new life as a vampire. The extra information about the meaning of the books' titles are from twilight saga wiki. I do not own it.
