I ran through all three covers with Matt, and decided on final designs. Went with a cloth background for the books, moved the border in and faded it just a touch, and completely redesigned the titles for all three books.

Also changed the gold border from rounded to squared, and thinned it down a bit. These aren’t quite as shockingly vivid thanks to the cloth overlay, and they’re much easier to read even at tiny sizes.
