Follow a little boy and a penguin on their little adventure up in the mountain in search of something very special—Lonely Not. Along the way, they found smallness, eternity, freedom, tranquility, trust, waltz of the water, songs of the mountain and eventually, each other. This simple yet poetic picture-book features beautiful water-colour illustrations inspired by the idyllic landscapes of outskirt Wonju (원주), Korea where the author stayed for near to 3 months while on a residency.
