The Little One by Kiyo Tanaka

One day, a young girl sees a mysterious little figure sitting on a wall. It seems to be following her through town on her way back home, so, curious, she goes to say hello: "Hello, little one, what are you doing here?" It's now her turn to follow the little one as it leads her to a garden and a cup of tea. And then, the pair enter a pitch-black closet and close their eyes, opening them to reveal... a magical attic that contains roots to hop over, trunks to hide in, vines to climb, branches to slide down. There's even an enormous, cuddly creature, so soft and warm and perfect for napping and dreaming! 
Though silent and unnoticed by anyone else, the little one forms a beautiful friendship with the young girl in the space of an afternoon, showing her affection and care and sharing with her the fun and healing that comes out of imagination and play. Each illustration in this beautiful book was created via a delicate copperplate etching by author-illustrator Kiyo Tanaka, lovingly crafted to depict a dream-like world full of friendship, where anything is possible.
