Saw these book covers, all on the same table in Waterstones and I couldn't resist putting them next to each other. This whole ‘silhouette of a person running/escaping/fleeing for their lives' thing is totally overdone. I guess it sells books though. What do you think – should we use a recognisable, visual trope as a signal to the reader, or should we strive for originality and take a risk? Comments welcome from writers, readers, cover designers and everyone else.
