I agree with the others. It is the whole package. The cover has to match the book. You wouldn't put a picture of cuddly kittens on the front of a book about vampires, unless of course we're talking about Kittens who are vampires. lol I am attracted to it all at once...but the final decision is made on the blurb. If the blurb doesn't catch me, chances are I won't read further. And I can usually tell within the first two paragraphs if I'm going to read the rest of the book.
