Although I'm a long way off ever needing to really worry about this, I got thinking today about the cover designs I'd like for my planned novels. Now I know that, should a publisher ever actually pick up my novel, they'll be the ones to make these decisions. So I'm thinking from a self-publishing perspective. And I know that, in that case, I can do whatever I want. However... Should each cover look the same? For example, if I were to chose some minimalist artwork for the first novel, should the following novels use a similar style of artwork? I imagine it would help potential readers spot your work, essentially building a brand. That seems to be what most publishers do; you can spot a Stephen King book or a Dan Brown book a mile away. Anybody here who's self published more than one book have any thoughts on the matter?
