When Debbie Carter learns that her teenage sister, Kimmi, has been brutally murdered, Debbie flies immediately to her parents’ home in Connecticut. Almost as soon as she has arrived, Debbie learns that there is much more to her sister’s murder than she initially realized.

Kimmi’s death was but one attack in a mysterious string of murders that have been cropping up in New England, all of which bear two things in common – the killers have all committed suicide after murdering their victims, and all of the killers kept journals with the same haunting poem scribbled manically across every page.

When Kimmi’s best friend, Jessica, is almost killed in a similar attack, Debbie becomes obsessed with getting to the bottom of the mystery.

Her investigations lead her to discover a mysterious MP3 music file that has been spreading through social networks like a virus, and a man named Harper Kyrie – a Musical Therapist in Boston, who appears to be at the heart of the enigmatic killing spree.

But Debbie has started having nightmares and hearing the cryptic MP3 song in her head, and begins to wonder if she may have gotten in too deep.
