Deo has always been alone — no herd, no name for what he is, only a strange horn he doesn't understand. When a storm drives him into a collapsed well, he falls into a city buried for centuries: a place built by hands and hooves working side by side. As he explores its silent halls and fading murals, Deo begins to piece together the truth of what happened there — and why unicorns disappeared from the world above. Violet Valley is a gently illustrated picture book about growing up, discovering what you're capable of, and finding where you belong — told through Deo's journey from solitary wandering to friendship, and from not knowing what he is to finally taking flight. Featuring warm, painterly full-page illustrations throughout, and a closing mural connecting Deo's world to the real history of life on Earth.
