Silver on the Tree is the fifth and final book in The Dark is Rising series by Susan Cooper. In it the five children introduced in the previous books attempt to vanquish the Dark for all time. In order to do that, they must figure out how to find the crystal sword.
Susan Cooper said that this book took two years to write, unlike most of her other book, which took about a year. She also said when finishing this book, she had "a combination of a sense of loss and a sense of relief. Finishing 'Silver on the Tree', I felt a great sense of loss, because there were all these people that I was never going to see again."
