I don't always agree. I've had stepback covers and they were really pretty.
Covers are a real problem to make everyone happy.
When writers are as big as Nora Roberts, all that the cover needs to sell is her name on it. I've really liked some of mine. The best thing you can do is to write the editors, using the address in the front of the book, and tell them what you think. Covers on the address. Publishers need to hear this.
