What does the covers of the "Twilight Series" represent? - flower edwards hardcore

I read here that the cover of Twilight that Bella Edwards is ..... forbidden fruit, but what is the flower of the New Moon, Eclipse Band and the average chess books? I think the board is a way that it makes the game "voturi" and how they are with their movements, etc. .. But I can not find the others!
