Part of the process has been discussing the character, the book, how to sum up the story with a single image and because it's part of a series, how to carry that image/theme though out the rest of the series. It got me thinking about a blog post. What makes a good cover?
For me, a good book cover should convey the mood of the story. If the front cover is all rainbows and puppies, I'm not going to be expecting to see angst within the pages. The opposite is true, a dark and depressing cover on the front of a comedy just doesn't work, unless of course it's a dark comedy. One example of great covers which perfectly convey the tone of the books are the Discworld series by Terry Pratchett. For the UK and Australian books the bright illustrations that wraparound the covers are fun and silly, and hint at the silliness that will be contained between the pages.
Do you ever judge books by their covers? Have you seen a cover and not read the contents? Conversely, have you found a great cover and the book just hasn't lived up to the expectation? I have to say I probably have done both.
