An avenging angel is meting out savage justice, and she’s far from through.</p><p>One by one, more children arrive at Mercedes’s door with the same horror story.

And each one taking its toll on her life and career.</p><p>Now, as the investigation draws her deeper into the dark, Mercedes is beginning to fear that if this case doesn’t destroy her, her memories might.</p>
