Ido. A great covers nudges me to read the synopsis and if its good, to read it. A not so well done cover doesn,t arouse my interest as much but i would still give it a shot if the story's good. I believe a book cover acts sort of like a promoter for the book. To state a few, i absolutely loved the cover of the book I'm currently reading, 'Cleopatra's daughter' when I saw it in another blogger's best book lists. Another example would be the book' The art of racing in the rain by Garth Stein really stole my heart with a very soulful looking doggy dog eyes on the cover.
