Sabrina Brooks is a bestselling author of gripping thrillers. Unlike her fictional characters, Sabrina lives a quiet life with her two beloved dogs. But behind this peaceful exterior is a dark, painful past. As a child raised by an emotionally distant father, Sabrina rarely felt love. And as an adult, she had to escape from an abusive marriage. Sabrina channeled that fear into her writing, and now she has everything she's ever wanted. Until the arrival of a mysterious letter disrupts it all.
