Sixteen-year-old Marshall Seaver is expecting a boring summer when his best friend goes away, but instead he finds himself haunted--and hunted--by ghosts that want something from him which he cannot decipher.

Marshall is forced to make a brave and shocking choice when the battle is on the line, and he and Cooper might be rewarded with help from someone quite unexpected."--Provided by publisher.
