NaBloPoMo prompt: How important are book covers in getting you to read a book.
Not very. The back cover description and/or a recommendation from a person or website I trust is probably the most important factor. I'll also read books that I'm completely unsure about if they're for a book club; I haven't managed to make it to a meeting yet but have been reading along for a few months for a vegan book club meetup group. I even read my first Stephen King novel (Under the Dome) for that group last month, and found it kind of disturbing, but not bad.
The one thing that can make or break a book choice, though, is if it's recently been made into a movie. Regardless of whether it's a book I've loved for ages, or one I've only even heard of because of the movie, I refuse to buy a book that has an image from the movie version on the cover, and let people who see it assume that I'm only reading the book because of the movie. It's an absolute dealbreaker!
Does a movie-based book cover affect your book choices positively or negatively?
