The Light of Western Stars by Zane Grey

"Stillwell!"

Madeline's cry was more than the utterance of a breaking heart. It was full of agony. But also it uttered the shattering of a structure built of false pride, of old beliefs, of bloodless standards, of ignorance of self. It betrayed the final conquest of her doubts, and out of their darkness blazed the unquenchable spirit of a woman who had found herself, her love, her salvation, her duty to a man, and who would not be cheated.
