In this wordless, all-ages graphic novel, our protagonist discovers a leaf that radiates a vibrant light. He returns to a detailed metropolis - depicted in sombre greys and blues - and searches for answers. During his quest, he stumbles upon a man who knows what's really happening in the city's labyrinthine ducts; a woman who spends her life studying and classifying obsolete flora; and the truth about the ever-dwindling environment. Leaf is a graphically stunning story that unfolds with a dream-like pace.
