Another book to add to my reading list! I read the inside flap for Mr. Penumbra’s 24-Hour Bookstore at the store the other day, and it intrigued me. When I came back and looked it up online, I found out the cover was actually glow in the dark. Too cool! It isn’t just a fun effect either; it supports the story. I also enjoy the simplicity of the bright rectangles (meant to be books) and the handwritten type paired together. Credit goes to Rodrigo Corral.
