The idea behind this was to create book sleeves that could cover the paperback edition of a novel. If someone doesn't like the cover of a book, they could purchase a book sleeve with an alternate cover they enjoy more. The sizing strays from the traditional hardcover sizing because it is meant for a paperback. It is also free of any description text since that would already be on the cover underneath the sleeve. 

Though I have not read them myself, some of my close friends hold If We Were Villains and The Secret History close to their hearts, so I created these as a personal project for them.
