"In this wordless, all-ages graphic novel, our protagonist discovers a leaf that radiates a vibrant life. He returns to a meticulously wrought metropolis -- depicted in somber grays 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."-- Page [4] of cover.
