One of the great joys of browsing for books in an actual bricks-and-mortar shop is the serendipity of it; the way you can go in looking for one thing and come out with three others that you didn’t even know you wanted. For unknown authors like me, who are publishing their debut novels in a media environment with ever-decreasing books coverage, being stumbled upon like this – thanks to an eye-catching cover or a well-written blurb – is one of the surest routes to readers.
