Valerie Hart

When the two strangers turn up at Rowena Cooper's isolated Colorado farmhouse, she knows instantly that it's the end of everything. For the two haunted and driven men, on the other hand, it's just another stop on a long and bloody journey. And they still have many miles to go and victims to sacrifice before their work is done.

Troubled San Francisco homicide detective Valerie Hart is planning a rare weekend away from the job when she gets the call. A body has been found. A woman, brutally murdered. And the cryptic note left by the body is addressed to Valerie. The victim is unknown to her, but as Valerie analyses the scene, the clues begin to point in a deeply disturbing direction: to a maximum security prison where a woman called Katherine Glass is awaiting execution for a series of gruesome killings.
