Ellery Wainwright and her husband, Luke, were supposed to spend their 20th wedding anniversary together at the luxurious Resort at Broken Point in Big Sur, California. But now she’s traveling solo. To add insult to injury, there’s a wedding at Broken Point scheduled during her stay. Ellery isn’t certain of anything except for her love for her kids and her growing realization that this place, though beautiful, is unsettling. When Ellery discovers the body of the groom floating in the pool in the rain, she realizes that she is not the only one whose future is no longer guaranteed. Before the police can reach Broken Point, a mudslide takes out the road to the resort, leaving the guests trapped. When another guest dies, it’s clear something horrible is brewing.
