I really enjoyed how each frame was filled with emotional content, this really went well with the dramatic black and white illustration. The lack of words never seems to take away from the story; instead its silent imagery adds to the open/conceptual ideas of the book, meaning our own emotions are free to run wild and add emphasis on emotion.
The main storyline of being out of your element and in a new world alone matches perfectly with this wordless medium; the main characters experiences become relatable. Immigrants often experience a difficult time transitioning into a different world, often one where they struggle to fit in and are unwelcome.
The addition of words would make the novel lose its openness to interpretation which is something that is critical for this storyline.
