2 warnings tho! It's pretty old school but that doesn't mean it can't be enjoyed by a younger reader (I'm not old myself either). I would compare it to bronze age Marvel, I got the same kind of enjoyment out of it (and also the awesome art).
Also, it's not strictly medieval more Arthurian but it doesn't have many magical elements (rarely any based on what I've read).
But those hcs are really nice looking, very tall books but not hard to handle at all.
