Cross Her Heart by Melinda Leigh

A homicide detective’s violent family history repeats itself in #1 Amazon Charts and Wall Street Journal bestselling author Melinda Leigh’s novel of murder, secrets, and retribution.

For more than twenty-five years, Philadelphia homicide detective Bree Taggert has tucked away the nightmarish childhood memories of her parents’ murder-suicide…Until her younger sister, Erin, is killed in a crime that echoes that tragic night: innocent witnesses and a stormy marriage that ended in gunfire. There’s just one chilling difference. Erin’s husband, Justin, has vanished.

Bree knows how explosive the line between love and hate can be, yet the evidence against her troubled brother-in-law isn’t adding up. Teaming up with Justin’s old friend, former sheriff’s investigator and K-9 handler Matt Flynn, Bree vows to uncover the secrets of her sister’s life and death, as she promised Erin’s children. But as her investigation unfolds, the danger hits close to home. Once again, Bree’s family is caught in a death grip. And this time, it could be fatal for her.
