Sleepless

While recuperating from a near fatal gunshot wound, FBI Agent Caden O'Connor is relegated to a desk job with the newly-formed Western Tri-State Cold Case Squad. Three months in, miserable, and on the verge of depression, an anonymous letter arrives and changes everything.

Hundreds of miles away, concert violinist Alaina Reynolds is having problems of her own. First, there's the fear that her psychiatrist wants to have her committed, then the voices that are driving her insane.

Nevertheless, when these long dead souls whisper in her ear and reveal clues that could send their killers to jail, Alaina risks all and becomes the Cold Case Squad's new informant.

But not without taking some precautions, as the Cold Case Squad's confidential informant is known only as SLEEPLESS.
