A Few Shining Hours — Jeanne Stephens

Once Kathleen had loved Quinn Gresham, and the sadness of what had followed haunted her until the day he walked back into her life. On that day sadness became anger.

He didn't know about the daughter he had given her, the infant who had so briefly brightened her life. But how could he fail to sense her pain at seeing him again? Apparently their one night had meant nothing to him, but it had meant the world to Kathleen. Despite the sorrow, the anger, the pain, in those few shining hours she had fulfilled a love that would last in her heart forever.
