Brandon Sanderson is an excellent author, and his books meet practically all of your requirements! There's romance in many of his books, but it's never the main focus, and it's well-written. The focus of his books tends to be more about the actual plot and story. Also, all of his books have really really cool magic systems. He's written a lot of books, but I recommend starting with Mistborn Era 1. Warning, most of his books are fantasy and/or sci-fi, so if you don't like that, it's not for you.
Hope this was helpful!
