"The spirit of Wren Noble is lonely even though she talks with her living twin sister Lark. Then Wren meets Noah, the spirit of a young man who died a century ago. But Noah has a dark influence on Wren and Lark's distrust of him drives the sisters apart for the first time in their lives. As Halloween approaches, Lark must find a way to stop whatever deadly act Noah is planning, even if it means going through her sister to do so."--Provided by publisher.
Wren, the ghost of a girl who died at birth, and Lark, her depressed misfit living twin, help a boy who saves Lark from a suicide attempt and who is being threatened by the malevolent spirit of a long-dead serial killer.
