This is from the brilliant gray318 . Wow do I love this cover (and many other things he / she / they've done). The interior is supposed to be as good; unfortunately, I didn't open it when I saw it in the bookshop.
One thing that really let me down, however: the super super glossy cover. It just seemed so inappropriate for the art, which has such a beautiful hand-drawn expressiveness to it. I wanted to feel this cover as much as look at it.
