There’s a great blog called “Pop Culture Junkie” that covers reading, movies, TV, music, etc. But the part I like best about her site is her comparisons of look-alike covers – some with the same cover art, same with the same model in a slightly different pose.
Like did you know the “editor” [widely regarded as the writer] of Go Ask Alice had a book out called Annie’s Baby that looks a lot like the cover of Story of a Girl (but as far as I can tell, the girls are not the same person]? Look and learn here.
