This book cover is outside my normal area of genre, but it’s intriguing and well-crafted. I normally go for fantasy, historical fiction, or some adjacent genre, and this is cozy historical mystery. So, sort of adjacent, I suppose.
The image is what caught my eye, the negative space in the spill of grain. That and the mosaic-tile framing, the amphora, all brings to mind ancient Rome, which is indeed where the story is set. One doesn’t need rich, bright colors to catch the eye – the image itself does that plenty. I might have increased the contrast on the series title at the bottom, or not put it over the darker part of the frame, but other than that, it’s lovely.
I agree, job one of any book cover is to grab attention, and this does that well.
