Beautiful Lie by Diane Chamberlain

An unsolved murder. A missing child. A lifetime of deception.

Twenty years after pregnant Genevieve Russell disappeared, her remains are discovered and Timothy Gleason is charged with murder. But there is no sign of the unborn child.

CeeCee Wilkes knows how Genevieve Russell died, because she was there. And she knows what happened to her missing infant, because two decades ago she made the devastating choice to raise the baby as her own. Now Timothy Gleason is facing the death penalty, and she has another choice to make. Tell the truth and destroy her family. Or let an innocent man die in order to protect a lifetime of lies.
