"And then something happened. Something monstrous! Suddenly it came. The Something. A very dangerous Something!" This picture book focuses on the far-reaching consequences of a singular traumatic event. Five-year-old Kim has unexpectedly experienced something terrible, and now everything is different. Memories of the massive event resurface, frightening the boy again or filling him with anger. Tensions arise within the family, and Kim's changed behavior also affects interactions within the children's group. And so the child feels "all alone. And so small." Fortunately, Kim has a strong helper by his side: Tim-Tiger. Together, they set off for the Park of Wonderful Things, where Yum-Yum, the old shaggy monster lady, is already waiting for them. With their picture book, the experienced authors invite readers on this journey.
