Oh I love Banana! This was a collection of short stories that, in true Banana style (or perhaps Japanese style) didn't follow my Western notions of linear storytelling with a beginning-middle-end, a conflict and resolution or clear plot points. Instead they are more like poetry, or a delicate painting, or the leaves of an elegant flower. They are delicate and elegant stories that provide a brief but deep look into a moment in someone's life, a glimpse into their souls. They are beautiful and satisfying.
The curiosity left by these stories is not "I wonder what happened next?" but "I wonder if that character still feels that way?"
