Silver on the Tree (The Dark is Rising Book 5)

The six servants of the Light - the Drew children, Will, Bran and the mysterious Merriman - have reached their last, desperate fight against the forces of the Dark. They face one final, daunting task: to find the crystal sword. Their search will lead them from their own world to the haunting, magical Lost Land between sea and shore - and they will each stare death in the face before the battle's final moments.
