The press copy describes Factory Summers as Guy Delisle’s “most personal book.” It’s a strange phrase for a cartoonist whose work often tends toward the autobiographical — but it’s hard to ignore. What begins as a memoir of teenage summers spent working the floor at a Quebec City paper factory ultimately grows into something deeper. Ultimately, the book is a mediation on the relationship between a son and his distant father. That dynamic is the heart of the story — a fact the cartoonist says he only truly recognized as he was deep into the work.
