Scott Pilgrim is a series of graphic novels by Bryan Lee O’Malley. My husband loves these. They’re travel size and they have a manga aesthetic to them, even though they're written by Canadian. (Manga is a style of comics popular in Japan. When these books are written in Japanese and translated into English readers have to read them back to front, so at the front of the book there is a stop sign that tells English readers how to read from right to left so they’ll understand the story.)
Ash’s favorite thing about these books is that in one of them there is a stop sign at the back of the book that states that it is the back of the book and the reader needs to go to the front.
