Do you judge a book by its cover?
Yes! My daughter just shared with me the cover of The Raising from GRGenius's blog over at Satisfaction for Insatiable Readers (a great blog by the way that you should follow) that looked like it was a book about an alien abduction when it was really a life-after-death, paranormal story. The cover is crucial to giving an accurate depiction of the book in a glance. Something that is hard to do and for covers that do it right - it is a sort of art form.
