After their lives fly off the rails, getting back on track takes everything they have left.

Davis Winger has it all. A respected engineer who designs roller coasters in theme parks across the country, he is deeply in love with his wife and has a beautiful young daughter and a happy home. Until an accident strikes on one of his rides. Nothing fatal - except to his career. And to his marriage, when a betrayal from his past inadvertently comes to light. In one cosmically bad day, Davis loses it all.

His sister, Molly, is at a crossroads herself. She’s coasting through a dire relationship with an incompatible man-child. And she’s a journalist whose deeply personal columns about mothers and daughters are forcing her to confront the truth about her own mother, who abandoned Molly and Davis years ago and disappeared.
