Sometimes not.  I remember my first ever book cover way back when I was tender-hearted.  The hero-protagonist looked like a thug.  I wept.  After that  I had a spate of novels published with covers the colour of boiled flesh, the sort you would’t want to pick up without gloves on your hands.  Then I’ve had covers with strange people on them who never appear in the story   ‘Who is this tudor person in red?’ I’ve been asked.  Don’t ask, I’m only the author.   Now I’m looking forward with great excitement to the cover for book three in the Hildegard series THE LAW OF ANGELS.  Watch this space!!
