I'm currently reading Daughter of Siena by Marina Fiorato. The writing is excellent and I highly recommend it. But what appealed to me first was the cover.
And you have to admit, even if you don't read historicals, that it appeals. I checked to see who the artist was and it turns out that it is none other than Larry Rostant! He is much loved by genre publishers and his artwork adorns covers for a great many fantasy novels the world over.
Check out his site.
