At the edge of the woods, there is a great tree. And if you peep carefully, you might just see some people who stand as tall as your thumb and have heads the size of hazelnuts. Sylvia prefers to be alone rather than play noisy games with the other Tree Keepers. But one day, she finds a baby bird in her favourite hiding place. As Sylvia and the bird become friends, she will learn that sometimes, things are better when you have someone to share them with.
