I adore book covers – graphics and illustration. I like a cover to encapsulate the whole book, which is a very tall order, or to focus on something that takes me to the heart of the book. The Association of Book Cover Designs (ABCD) has annual competition for the best. The shortlist of the 2016 entries had some spectacular, delightful covers – my favourites are here, but look at the whole shortlist for 2016, 2015 and 2014. Which are your favourites, and which would you choose if you were the judge?
