On the Edge

The past is the past. Things buried back there should stay buried. No such luck.It's hard enough to figure out how something happened last week. But twenty years ago? Where do you even start? That's exactly what Mackenzie Prentice is asking herself this time.It's been over two decades since the girl went over the cliff. The official ruling was suicide, but her family never accepted that. Now the girl's mother is dying and needs to know for sure. She hires Mack. The girl's grandfather sends reinforcements from The City to help in the investigation. That help feels like interference, putting Mackenzie on edge.Also on edge? Her mother, her grandmother and, it seems, the world in general in a hot, steamy summer. Record heat and humidity fuel the tension in Three Rivers along with endless rumbles of thunder and a tornado warning that could not possibly come at a worse time.Mack is thirty-five, has a touch of OCD, is addicted to sugar, may occasionally drink too much, and has those incessant voices in her head commenting on her choices. In this fourth book of the Mackenzie Prentice Mysteries, she's in a race against time, matching wits with a savvy ex-cop. Who will find the truth first? Who will go over the edge?
