Hi all, I am looking for a book that is three stories in one as I remember. One of the stories is about a young girl left in the castle for the winter while her mother goes off, can't remember why. The young girl finds a boy out on one of the roofs in the cold and snow and brings him in. Another part of the book is about these creatures that hang "silks" in the trees where they live, and maybe sing to them? And I don't really remember the last part of the book. I hope someone has read this and can tell me something about the book. Thanks for your help.
