We have a long way to go, sighed the boy. Yes but look how far we have come, said the horse. Charlie Mackesy invites us into the world of the characters he has created and shared on Instagram since 2016. They have existed in his head for far longer than we have known them. In this beautiful tribute to their friendship, Charlie shares the full story of how they first met and their most important life lessons, through his illustrations and moving captions. The book will include new, never-before-seen, and his most beloved illustrations.
