The Winds of Summer — Arlene Hale

Fleur Lansing was happy in her job as a sociology teacher at Mitchell University. Vivacious, self-assured, she was a young woman to whom success came easily and for whom life, despites its occasional setbacks and disappointments, was glowing with promise. And excitement as well, particularly in the person of the attractive stranger who had suddenly asked her to dance at the university's annual masquerade ball--and who then disappeared just as mysteriously without leaving a clue to his identity.

How different was Fleur's young sister Jill, who showed and absolute talent for getting hurt by those she unwisely trusted, and for getting into situations that betoken only trouble. Fleur was usually not the type to interfere, no matter how much she loved Jill and worried about her. But when she heard that her sister was seriously involved with Paul Frazer, and older man known around Cranfield for his unsavory reputations, Fleur had little choice but to yield to her parents' entreaties and speak to Jill.

So she packed her suitcases and returned to her family and Gold Rush City, a thriving Wild West tourist attraction where she had taken a job for the summer. Fleur didn't realize it, but the season had come when she and her sister, and the men in their lives, found themselves caught up in a scheme of evil that threatened to destroy all of them.
