Exactly. The book's cover should reflect the content or style of a book because it does leave an impression upon the reader, especially in the case that you're mentioning. Yet it is also true when selecting a book that I am aware of. I've read everything from academic texts to flow blown manga about children with autism, but I probably wouldn't have read many of those books if their covers were jumbled around because there would be too much discordance.
