Lost Hills by Lee Goldberg

Now Eve, with a lot to learn and resented by her colleagues, has to justify her new badge. Her chance comes when she and her burned-out, soon-to-retire partner are called to the blood-splattered home of a missing single mother and her two kids. The horrific carnage screams multiple murder—but there are no corpses.

Eve has to rely on her instincts and tenacity to find the bodies and capture the vicious killer, all while battling her own insecurities and mounting pressure from the media, her bosses, and the bereaved family. It’s a deadly ordeal that will either prove her skills…or totally destroy her.
