I can remember that the book was a dark green velvet cover. It was about a fairy who lived in a city and could only touch things that were alive in order for her to stay alive. She would travel through the city touching moss and plants like that. I was given this book a a gift and lost it while moving homes, it was a great childhood book and I read it around 2007-2011. Any help would be appreciated!!
