The Forgiving Hour — Robin Lee Hatcher

After years of bitterness and anger over her ex-husband's betrayal, Claire Conway's life finally seems to be on track. She has raised a fine son, Dakota. Her work is going well, and for the first time in years she finds herself attracted to a man once again! Then Dakota brings home his fiancee, Sara Jennings, and everything falls apart. For Sara turns out to be the same woman Claire's husband had an affair with twelve years before. Forgiving Sara seems impossible. Yet only in that hour of forgiveness can the three of them be truly set free.
