Since she was a little girl, Melinda Gordon could talk to the dead: ""earthbound spirits"" as her grandmother called them. Melinda came to understand that the spirits are trapped, and in need. She listens, tries to understand what keeps them from crossing over, and helps them find what they need to be free. It's not easy, but with time and patience her gift allows her to come to bring those spirits to peace.

The sound of a mournful lullaby has been haunting Melinda in her sleep, the song of a ghost who doesn't seem ready or willing to accept her help. Knowing that earthbound spirits are often confused and troubled, Melinda feels that with time she will make a connection. But there is no time; the melodic tapestry that the ghostly singer is weaving with her words -- meant to comfort a child -- has become a trap, lulling the young listeners into such a deep sleep that no one can ever awaken them. It takes one child, then another and another, until all across the town children are drawn in by the gentle song, their lives slowly slipping away. Even Melinda, with her knowledge of the spirit world, finds herself being pulled into the beautiful snare, where she nearly loses herself. Only then does Melinda begin to worry that this is a spirit so troubled, so heartsick, that it may be beyond her help.
