Twilight-
This is legit what I thought when I looked at the book covers...

Twilight- Oh.. there's an apple on the cover. And her skin is really white... oh! Snow White! Maybe this is one of those stories about Snow White! And maybe a lot of things happen at twilight?
New Moon- Um. Rose? Maybe it's about a family who really likes gardens? Or... a boy who gets a girl flowers everyday? Kind of at a loss here...
Eclipse- Ribbons! Maybe it's about a big ceremony or something? And the main character has to cut the big ribbon? Or maybe ribbon dancers??
Breaking Dawn- Chess! It's one of those really intense chess matches, right? I KNOW I got that one right.

*finds out it's about a glitter glue/new girl romance*

Me- REALLY??????????????????

Harry Potter has amazing covers that actually relate to the story. Not just pictures that even I could take.
