Zane Grey 
The Light of Western Stars [EPUB ebook] 

Madeline Hammond wanted more out of life than the superficial glitter of New York society. So she bought a ranch near the turbulent Mexican frontier and ended up getting more than she’d ever bargained for-and most of it trouble! She has a lot to learn about running a ranch in frontier New Mexico, but there is no question in her mind that she has to intervene when Gene Stewart, a cowhand who risked his life to save her honor, is scheduled to be hanged. And Madeline Hammond rode into the lawless wilds of Mexico in a desperate bid for his life and the love she had suddenly discovered! A surprising climax brings the story to a delightful close.
