How much does the cover of a book influence the way you read it? Are you willing to pay more for the same book but with a better cover? Are you more likely to read a book if it has an intriguing cover?
General discussion about the physical appearance of books
I dislike when books have pictures of the characters on the cover. Every reader will arrive at an idiosyncratic idea of what a character looks like within the confines of the author's description. To have a picture of the character is imposing someone else's interpretation onto yours before you even begin the book.
I'll agree with that, but I do think having a representation of a character can be useful. When there is a character shown do you have trouble visualizing your own interpretation without the influence of the cover?
