They have the perfect marriage. Did one of them kill to get it?

Prep school sweethearts Ian and Andi Copeland are envied by everyone they know. They have successful businesses, a beautiful house in St. Louis, and their eldest daughter, Cassidy, is following in their footsteps by attending prestigious Glenlake Academy. Then, a submerged car is dredged from the bottom of a swimming hole near the campus. So are the remains of a former writer-in-residence who vanished twenty years ago-during Ian and Andi's senior year.

When Cassidy's journalism class begins investigating the death, Ian and Andi's high school secrets rise to the surface. Each has a troubled link to the man whose arrival and sudden disappearance once set the school on edge. And each had a reason to want him gone. As Cassidy unwittingly edges closer to the truth, unspoken words, locked away for decades, will force Ian and Andi to question what they really know-about themselves, about the past, and about a marriage built on a murderous lie.
