In the middle of a frozen lake, a girl is skating. She's not supposed to be here. No one is. Not since Kit Barrington died at Frost Hollow Hall ten years ago. But the dead don't scare Tilly Higgins. The ice is thin. It cracks. Suddenly she's under the water, drowning. Near death, a strange spirit appears to her, a boy so beautiful Tilly's sure he's an angel. But he's a ghost. A very troubled ghost. And he desperately needs her help.
