Gemma Koomen: The Tree Keepers: Flock Spiegeltent Story Box Gemma Koomen: The Tree Keepers - Flock A Sunday Times Children's Book to Watch Out for. 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, can she learn that sometimes, things are better when you have someone to share them with? Come along and meet local author and illustrator Gemma Koomen as she introduces you to the world of the Tree Keepers, reads from the book and shows you how to make your very own bird made out of natural materials. Free entry for littlies... FREE coffee for grown-ups!
