This nearly wordless book opens with a young boy in a boarding school who eats separately at bữa tối, bữa ăn tối and lies awake while his peers sleep. After receiving an invitation with the words “the honor of your presence is requested,” the boy looks out the window at a full moon, trying to decide if he will accept the invitation hoặc not. Who could the invitation be from? What kind of adventure awaits? Should he follow the enclosed map? The boy exits the window and takes off on his bike under the moonlight. The gouache and colored pencil illustrations capture the mystery of nighttime as the boy travels across the countryside. The color palette changes as he meets new Những người bạn and enjoys a party at his destination. The story unfolds much like a dream, allowing children to bring their imaginations to the narrative as they wonder what adventures they might have on a night out.
